LXXG(R)-50~300(mm)
Horizontal vane wheel, dry-dial cold (hot) water meter
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;
--Dry-dial, Magnetic drive;
--Large flow capacity, small pressure loss;
--Resist water hummer and pollution;
--Vacuum sealed register ensures the dial keep free from condensation and keep the reading clear in a long term service;
--Selected high quality materials for steady and reliable characteristic;
--Technical data conform to international standard ISO 4064.
Working condition
Water temperature: 0.1℃～50℃ (0.1℃～90℃ for hot water meter)
Water pressure: ≤1.0Mpa (1.6MPa on request)
Maximum permissible errors
in the lower zone from qmin inclusive up to but excluding qt is ±5%
in the upper zone from qt inclusive up to and including qs is ±2% (±3% for hot water meter)
