PRODUCT INFO:

FlowVis Digital is the latest and most significant upgrade to date to the renowned FlowVis family.

By adding Digital functionality to the already unrivaled accuracy and flexibility of FlowVis flow meters, users will now experience even greater functionality, ease of use, and precision. Unique features such as Pool Turnover Rate and an ability to set flow rate alarms, will further enhance the industry’s most respected flow meter.

FlowVis Digital employs a patented electronic design to accurately measure the flow rate. A remote digital display, housed in a NEMA 4X corrosion proof enclosure, displays the flow rate in both a numeric value as well as in a bar-graph format. Even with the ability to install FlowVis in tight spaces and with almost zero straight pipe requirements, it can sometimes be difficult to install the device in a location that makes it easy to read.

FlowVis Digital solves this problem by allowing you to install a Digital readout in a user accessible location. In addition to greater installation flexibility, the Digital upgrade will also eliminate the possibility of experiencing a parallax error issue when reading the standard FlowVis. Note: Parallax error can be caused by not looking at the FlowVis scale squarely – akin to a passenger in a car looking at the speedometer and seeing a different reading to the driver. Additional details relating to this, can be found in the FlowVis Operating Manual.

Using the ‘Advanced Setup’ features, FlowVis Digital can be interfaced with other systems such as heaters, chemical feeders and UV units, so that they will only operate above a user-defined flow rate.

When using this option, it will be necessary to include the Auxiliary Interface Unit with your purchase. FlowVis Digital also includes a 4-20 mA output that can be interfaced to Variable Frequency Drives, such as H2flow’s Eco-Flow in order to achieve constant flow control

Understanding Pump Affinity Laws

Understanding pump affinity laws will allow you to explain, demonstrate and calculate how a change in motor speed impacts;

• flow rates against resistance

• power consumption

• operating costs

1. The change in flow is proportionate (equal) to the change in speed. If we halve the speed we halve the flow

2. The change in pressure is equal to the speed change factor squared. Operating pressure will be 1/4 of the original pressure

3. The change in power consumption is equal to the speed change factor cubed. Power consumption will be 1/8 the original consumption

As an example, if we take a pump with the following characteristics:

• Motor speed: 2850 rpm

• Flow rate: 302 lpm

• Pressure: 8 metres head

• Power input: 983 Watts

We set the low speed at 1900 rpm – a reduction factor of 0.67 - 1900 ÷ 2850 = 0.67 Applying the factor 0.67 to all pump affinity laws we can determine the pumps operating characteristics at the new speed on 1900 rpm.

1. The change in flow is proportionate (equal) to the change in speed. 302 x 0.67 = 202 lpm

2. The change in pressure is equal to the speed change factor squared. 8 x 0.67 x 0.67 = 3.6 metres head

3. The change in power consumption is equal to the speed change factor cubed. 983 x 0.67 x 0.67 x 0.67 = 295 watts

Therefore, the pump has these new low speed operating characteristics:

• Motor speed: 1900 rpm

• Flow rate: 202 lpm

• Pressure: 3.6 metres head

• Power input: 295 watts

• Power input: 983 Watts

We set the low speed at 1900 rpm – a reduction factor of 0.67 - 1900 ÷ 2850 = 0.67 Applying the factor 0.67 to all pump affinity laws we can determine the pumps operating characteristics at the new speed on 1900 rpm.

1. The change in flow is proportionate (equal) to the change in speed. 302 x 0.67 = 202 lpm

2. The change in pressure is equal to the speed change factor squared. 8 x 0.67 x 0.67 = 3.6 metres head

3. The change in power consumption is equal to the speed change factor cubed. 983 x 0.67 x 0.67 x 0.67 = 295 watts

Therefore, the pump has these new low speed operating characteristics:

• Motor speed: 1900 rpm

• Flow rate: 202 lpm

• Pressure: 3.6 metres head

• Power input: 295 watts

Understanding Pump Affinity Laws

Understanding pump affinity laws will allow you to explain, demonstrate and calculate how a change in motor speed impacts;

• flow rates against resistance

• power consumption

• operating costs

1. The change in flow is proportionate (equal) to the change in speed. If we halve the speed we halve the flow

2. The change in pressure is equal to the speed change factor squared. Operating pressure will be 1/4 of the original pressure

3. The change in power consumption is equal to the speed change factor cubed. Power consumption will be 1/8 the original consumption

As an example, if we take a pump with the following characteristics:

• Motor speed: 2850 rpm

• Flow rate: 302 lpm

• Pressure: 8 metres head

• Power input: 983 Watts

We set the low speed at 1900 rpm – a reduction factor of 0.67 - 1900 ÷ 2850 = 0.67 Applying the factor 0.67 to all pump affinity laws we can determine the pumps operating characteristics at the new speed on 1900 rpm.

1. The change in flow is proportionate (equal) to the change in speed. 302 x 0.67 = 202 lpm

2. The change in pressure is equal to the speed change factor squared. 8 x 0.67 x 0.67 = 3.6 metres head

3. The change in power consumption is equal to the speed change factor cubed. 983 x 0.67 x 0.67 x 0.67 = 295 watts

Therefore, the pump has these new low speed operating characteristics:

• Motor speed: 1900 rpm

• Flow rate: 202 lpm

• Pressure: 3.6 metres head

• Power input: 295 watts

Understanding Pump Affinity Laws

Understanding pump affinity laws will allow you to explain, demonstrate and calculate how a change in motor speed impacts;

• flow rates against resistance

• power consumption

• operating costs

1. The change in flow is proportionate (equal) to the change in speed. If we halve the speed we halve the flow

2. The change in pressure is equal to the speed change factor squared. Operating pressure will be 1/4 of the original pressure

3. The change in power consumption is equal to the speed change factor cubed. Power consumption will be 1/8 the original consumption

As an example, if we take a pump with the following characteristics:

• Motor speed: 2850 rpm

• Flow rate: 302 lpm

• Pressure: 8 metres head

• Power input: 983 Watts

We set the low speed at 1900 rpm – a reduction factor of 0.67 - 1900 ÷ 2850 = 0.67 Applying the factor 0.67 to all pump affinity laws we can determine the pumps operating characteristics at the new speed on 1900 rpm.

1. The change in flow is proportionate (equal) to the change in speed. 302 x 0.67 = 202 lpm

2. The change in pressure is equal to the speed change factor squared. 8 x 0.67 x 0.67 = 3.6 metres head

3. The change in power consumption is equal to the speed change factor cubed. 983 x 0.67 x 0.67 x 0.67 = 295 watts

Therefore, the pump has these new low speed operating characteristics:

• Motor speed: 1900 rpm

• Flow rate: 202 lpm

• Pressure: 3.6 metres head

• Power input: 295 watts

Understanding Pump Affinity Laws

Understanding pump affinity laws will allow you to explain, demonstrate and calculate how a change in motor speed impacts;

• flow rates against resistance

• power consumption

• operating costs

1. The change in flow is proportionate (equal) to the change in speed. If we halve the speed we halve the flow

2. The change in pressure is equal to the speed change factor squared. Operating pressure will be 1/4 of the original pressure

3. The change in power consumption is equal to the speed change factor cubed. Power consumption will be 1/8 the original consumption

As an example, if we take a pump with the following characteristics:

• Motor speed: 2850 rpm

• Flow rate: 302 lpm

• Pressure: 8 metres head

• Power input: 983 Watts

We set the low speed at 1900 rpm – a reduction factor of 0.67 - 1900 ÷ 2850 = 0.67 Applying the factor 0.67 to all pump affinity laws we can determine the pumps operating characteristics at the new speed on 1900 rpm.

1. The change in flow is proportionate (equal) to the change in speed. 302 x 0.67 = 202 lpm

2. The change in pressure is equal to the speed change factor squared. 8 x 0.67 x 0.67 = 3.6 metres head

3. The change in power consumption is equal to the speed change factor cubed. 983 x 0.67 x 0.67 x 0.67 = 295 watts

Therefore, the pump has these new low speed operating characteristics:

• Motor speed: 1900 rpm

• Flow rate: 202 lpm

• Pressure: 3.6 metres head

• Power input: 295 watts

Cost of unit £972.00

Suggested Cost of installation £350.00

Total cost £1322.00

Based on electricity at 34p per kWh

The cost of running the pump at 80% of the speed for 95% of time and 100% of speed for 5% (backwash) is £8914 Per Annum.

Cost saving is £272 per month and 5 months payback on purchase & installation.

Understanding Pump Affinity Laws

Understanding pump affinity laws will allow you to explain, demonstrate and calculate how a change in motor speed impacts;

• flow rates against resistance

• power consumption

• operating costs

1. The change in flow is proportionate (equal) to the change in speed. If we halve the speed we halve the flow

2. The change in pressure is equal to the speed change factor squared. Operating pressure will be 1/4 of the original pressure

3. The change in power consumption is equal to the speed change factor cubed. Power consumption will be 1/8 the original consumption

As an example, if we take a pump with the following characteristics:

• Motor speed: 2850 rpm

• Flow rate: 302 lpm

• Pressure: 8 metres head

• Power input: 983 Watts

We set the low speed at 1900 rpm – a reduction factor of 0.67 - 1900 ÷ 2850 = 0.67 Applying the factor 0.67 to all pump affinity laws we can determine the pumps operating characteristics at the new speed on 1900 rpm.

1. The change in flow is proportionate (equal) to the change in speed. 302 x 0.67 = 202 lpm

2. The change in pressure is equal to the speed change factor squared. 8 x 0.67 x 0.67 = 3.6 metres head

3. The change in power consumption is equal to the speed change factor cubed. 983 x 0.67 x 0.67 x 0.67 = 295 watts

Therefore, the pump has these new low speed operating characteristics:

• Motor speed: 1900 rpm

• Flow rate: 202 lpm

• Pressure: 3.6 metres head

• Power input: 295 watts
