Product Description
Removable element woltman cold (hot) water meter DN50~DN500
This type of water meter can be used for a remote reading transmission system as equipped with a built-in sensor.
Application
--Measuring the volume of cold (hot) water passing through the pipeline
Feature:
--Removable element structure, easy installation and maintenance, register for universal use within this range detachable without Removing the meter from the pipeline;
--Dry-dial, Magnetic drive sensitive action, small pressure loss;
--Vacuum sealed register ensures the dial keep free from fog and Keep the reading clear in a long term service;
--Selected high quality materials for steady & reliable characteristic;
--Technical data conform to international standard ISO 4064.
Working condition
Water temperature: 0.1C~40C ( 0.1C~90C for hot water meter)
Water pressure: ≤1Mpa (1.6MPa for special requirement)
