Water Meter range from AWE including Cold Water Meters, Hot Water Meters and Flanged Water meters

Water Meter

Water meters are designed to be permanently installed into pipework to accurately measure the flow and totalise the flow running within the pipework.

Depending upon the size of the pipework we offer two different types on water meter. The first is our BSP threaded Water Meters - these are designed for either hot water and for cold water.

Each water meter has a threaded inlet and threaded outlet making screwing them into pipework as simple as possible. These are available in sizes up to 2" BSP and as small as 1/2" BSP.

The second type is our Flanged Water Meter range, these are designed for larger diameter pipework with a minimum size of 2" diameter, and up to a maximum of 8" diameter.

Water Meter Principle of Operation

Both types of water meter to accurately measure the amount of water passing through the body of the water meter using a high sensitivity turbine sensor, which drives a large and accurate gear train.

The gear train outputs both a digital signal, also known as a pulsed signal, as well as a totalisation counter, which is displayed directly on the screen.

Totalising Water Meter

The totalisation counter provides an accurate way of measuring the total amount of water that has passed the water meter.

The mechanical counter is non-resettable and displays directly on the front face of the water meter.

Pulsed Output Water Meter

As well as driving the totalising counter, the mechanical gear train outputs a digital signal / pulsed output.

This is a volt free pulse which is directly proportional to the flow. As the flow rate increases the number of pulses output by the water meter increases, this relationship is directly proportional and the pulsed output from the water meter can be fed into a control panel, BMS, PLC, or directly in to a dosing pump.

Water Meter K Factor or Constant

Each water meter is manufactured with a water meter K factor or water meter constant, this is factory set and specified when the water meter is ordered.

The K-Factor defines the number of impulses per litre that passes the water meter, please see our chart below for a list of available K factors and the corresponding flow rate per pulse:-

K Factor (Constant)Litres per Pulse
K = 0.25 0.25 Litres / Pulse (250ml / pulse)
K = 1.0 1.0 Litres / Pulse
K = 10.0 10.0 Litres / Pulse
K = 100.0 100.0 Litres / Pulse
K = 1000.0 1000.0 Litres / Pulse (1m3/ Pulse)

The pulsed output is very useful and can be used to drive dosing pumps for proportional biocide dosing in cooling water and drinking water applications, it can also feed into batch control units, as a well as a whole host of instruments for process control applications.
