Municipal Water Meters
LXGR is a hot type irrgation water meter, designed to measure the total volume of unidirectional water passing through large pipeline in sizes of 40mm to 300mm, such as tap water, well water, river water, as well as sewage, except corrosive water.
Features
* Magnetic drive, lower transmission resistance.
* Magnetic shield, for external magnetic field protection.
* Removable structure, easy maintenance.
* Sealed dry dial register ensures clear reading, long working life.
* The measuring mechanism can be removable from the body for checking, maintaining and replacing, and the body needn't be dismantled from the pipeline.
* Inter-exchangeable parts.
* High flow capacity, Low pressure loss, water impact resistance and anti-pollution.
* Can be equipped with reed switch (register can't rotate). Standard Compliance Technical data conforms to ISO 4064 Class A, R20, R25 standard
Working Conditions
Water temperature: ≤50ºC for cold water meter
Water temperature: ≤90ºC for hot water meter
Water pressure: ≤1MPa or 1.6MPa or 4.0 MPa optional (10bar or 16bar r 40 bar optional)
Installation requirements
*A horizontal position with the register face upwards is recommended.
*Pipeline must be flushed before installation.
*The meter should be constantly full of water during operation.
Maximum Permissible Error
In the lower zone from Qmin(Q1) inclusive up to but excluding Qt (Q2) is ±5%.
In the upper zone from Qt(Q2) inclusive up to and including Qmax(Q4) is ±2%(cold water meter).
In the upper zone from Qt(Q2) inclusive up to and including Qmax (Q4) is ±3% (hot water meter).
