Water Meters



The various Dayliff water meter types are robust and economical designs for monitoring residential, commercial and agricultural consumption. All meters are remote monitoring enabled and pulse cables are available on request. Sizes are available from DN15 to DN100 in three different ranges as follows:-

MJ
A high precision and reliable multi jet dry type water meter designed for general water supply metering applications. It features magnetic drive for lower transmission resistance, a magnetic shield for external magnetic field protection and a sealed dry dial to ensure clear and easy reading. The body is made from composite plastic for DN15 and DN20 sizes and brass for larger sizes. Meters are supplied with inlet strainers and union connectors.

PD
Rotary piston type meters that provide high accuracy over a wide flow range. The mechanical transmission movement provides reliability and the liquid sealed register provides easy and clear reading. Meters are fitted with internal strainers, non return valves and union connectors and the bodies are made from composite plastic (15mm size) and corrosion resistant steel for other sizes.

WP
A heavy duty meter with flange connections for bulk flow applications featuring magnetic drive, a dry dial for clear reading and a removable measuring mechanism that can be maintained without removing the meter body. The body is made from cast iron with epoxy coating.
