Displacement Volumetric Water Meter

 

Introduction

 

This range of water meter is used to measure the total quantity of cold(hot) potable water which consumed in household or a resident unit, passing through the pipeline.

 

Specifications

CLass C,brass body,with a pair of connectors


Features

Rotary piston system.long service life

Dry-dial or liquid sealed register,keeps clear reading for long time°c

High measuring accuracy,the starting flow of the meter is 2 L/Pulse or less

Can be installed in any position

Brass body,m³  or gal,optional

Remote transmisson can be added upon request

Many kinds of sensors,such as Reed Switch,Hall and Weagand can be supplied upon request;

Pulse output maybe 1L/Pulse

ISO 4064 :1993 Class C

ISO 4064:2005 R160/R200

 

Working condition
