CWFA50
2" Flanged Water Meter
2" flanged water meter for measuring the volume of flow through pipe work with pulsed output and flow totalisation.
2" Flanged Water Meter CWFA 50 Introduction
The CWFA 50 is a 2" flanged contacting head water meter manufactured with a cast iron body for use with clean water and ideally suited for process applications where accurate measurements of large volumes of water flow are required.
Designed for use with clean water, such as towns water, the CWFA 50 is rated to a temperature up to 30°C and a pressure of up to 16 Bar. The CWFA 50 may be installed in any position and provide precision flow measurements with a maximum normal flow rate of 15 m3 / Hr.
The robustly constructed water meter is designed to be bolted to connecting flanges in pipework to become a permanently installed flow meter, allowing the 2" (50mm) flanged water meter to measure the flow passing through it.
The 2" flanged water meter CWFA 50 has a high sensitivity turbine impulse under which drives a large accurate gear train to provide both totalisation and the pulsed output.
By design, the turbine is the only moving part of the water meter in contact with the water itself, this is so that the we can offer exceptional operating life from our CWFA series of flanged water meters.
2" Flanged Water Meter With Pulsed Output
The CWFA 50 water meter has a high sensitivity turbine impulse sensor. The turbine sensor is both antimagnetic and non-hygroscopic and drive a large and accurate gear train.
The resulting digital signal is via pulsed volt free contacts proportional to the flow rate - the K Factor of the 2" (50mm) Flanged Water meter CWFA 50 is K = 10.0, giving 1 pulse per 10 litres.
The pulsed output signal is rated at 24 V - 0.2 A and the initial supplied cable length is 2 metres.
The CWFA 50 can be easily integrated into a dosing pump, batch controller, external counter or other piece of process control equipment that corresponds to a pulsed input proportional to liquid flow rate.
2" Flanged Water Meter With Totalisation
As well as delivering a pulsed output signal our the CWFA 50 has a mechanical non-resettable counter which is displayed on the front of the water meter. The 5 digit mechanical counter displays the total volume of liquid that has flowed through the water meter in M3.
The mechanical counter and water meter frontage are covered in a transparent cover manufactured in clear epoxy resin.
2" Flanged Water Meter CWFA 50 Features & Benefits
The CWFA 50 is an excellent way of measuring clean water entering a process. Used frequently on evaporative cooling tower make up water, softener feed water, in plating baths makeup water, to control flow proportional dosing and in any application where the volume of water flowing in a pipeline needs to be accurately measured.
The CWFA 50 is of simple design and proven construction - designed to provide reliable, accurate and dependable measurement and control of many industrial processes, and as the CWFA 50 is a water meter with 2" (50mm) flanged connections, securing it in place for a long operational life is as simple as possible.

Features
- Cast water meter with high sensitivity turbine sensor designed specifically for process control applications using clean water.
- The high sensitivity non-magnetic and hygroscopic impulse sender drives a large accurate gear train to ensure precision totalisation counts and pulsed outputs.
- No gears in the wetted area, the only moving part in contact with the water is the impeller.
- Pulsed output with a K = 10.0 constant to give 1 pulse per 10 litres of water - ideal for counting incoming makeup water.
- Totalisation is displayed on a mechanical non-resettable counter allowing the total volume of water that has passed through the water meter to be monitoring dependably and easily.
- Proportional digital pulsed output signal which corresponds to the K constant - provides a useable signal to external control devices such as batch counters, controllers, dosing pumps and other control equipment.
- Proven design of simple & construction to provide reliable, accurate, and dependable measurement and control of many industrial processes.
