Operation description

Please see the diagram of the two reed switches system below, the two reed switches woud be operated “ON” OR”OFF” respectively by the magnet fitted to the pointer or gear during its running on the register,but never “ON” at the same time ,unless the out- magnet attackes. The two reed switches operate two “ON” and two “OFF” in one round of the pointer or the gear means one signal output,this principle prevent the loss or overcounting of the signal output due to the switches joggling or the pipe vibrating ,so assures reliability of the signal output.

 

Application

--Measuring the volume of cold potable water passing through the pipeline.

Feature

--Single-jet, dry-dial, free rotating register, small in size and light in weight;

--Magnetic drive, Resistance to exterior magnet interference,

--keep the reading clear in a long term service;

 

Note

--Measuring accuracy conform to ISO 4064 class B standard..

--Available with different length on request. Available in hot water meter on request.

Working condition

--Water temperature:   0.1℃~40℃ ( 0.1℃~90℃for hot water meter)

--Water pressure   : ≤1.6Mpa

Maximum Permissible Error

(1) in the lower zone from qmin inclusive up to but excluding qt is ±5%

(2) in the upper zone from qt inclusive up to and including qs is ±2%

Hot water meter ±3%
