S20MJC- 20mm WRAS Cold Water Meter c/w Pulse, Qp 4

The Pulsed Cold Water Meter (20mm, 3/4″ BSP TM) is designed for accurate monitoring of cold water consumption, typically linked to energy monitoring systems. Featuring a 20 mm nominal bore and 3/4″ BSP TM thread, this meter ensures precise measurement with a pulse rate of 1 pulse per litre.

Built with a durable cast copper alloy body, the meter uses a multi-jet and vane-wheel mechanism and meets MID standards for accuracy up to R100-H in horizontal installations.

It has a maximum capacity of 4 cubic metres per hour and can handle pressures up to 16 bar. WRAS-approved, this meter suits cold-water applications with a maximum temperature of 30°C.

The Pulsed Cold Water Meter offers a reliable and accurate solution for monitoring water consumption, with robust construction and compliance with key industry standards.

Qp = permanent (nominal) flow rate
4 m³/h = 4,000 litres per hour ≈ 66.7 litres per minute ≈ 1.11 litres/second

For example, a meter marked Qp 4 is typically intended to measure accurately around a continuous flow of 4 m³/h, although it can usually handle a higher flow for shorter periods.
