remote monitoring enabled and pulse cables are available on request. Sizes are

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.
