Cold water meter range with digital output and flow totalisation

Cold Water Meter

Our range of cold water meters are designed to measure the volume of cold clean water, such as towns water passing through the water meter. The temperature of the water passing through the water meter can be up to 30°C and a pressure of 10 Bar.

Designed for process control applications our cold water meter range are commonly used on supply water flowing into a water softener, evaporative cooling tower, metal finishing line, or any other piece of process plant requiring the volume of water in it to be accurately measured and totalised.

Cold Water Meter Installation

Our cold water meters are supplied with BSP threaded couplings allowing the water meters to be directly installed into pipework as a permanent measuring device.

The high sensitivity turbine drives a large accurate gear chain to give precision measurements for the non-resettable totalising counter as well as driving a pulse output corresponding to the flow rate.

Cold Water Meter Pulsed Output

The pulsed output from each of the brass bodied water metres is a volt free signal corresponding to the water meters rated K Factor or Constant.

Our full range of cold water meters are listed below:-
