Product Description

Single-jet Ultrasonic Heat Measure Meter,Single-Jet T
ype Heat Measure Meter,Mechanical Single-Jet  Heat Measure Meter







 

Application

The range of heat measure meter is used to measure the total quantity to heat consumption passing through the central heating system, It consist of three part: flow meter, pairing temperature sensor and calculator.

 

Features:

1 .Uses the battery power supply, the effective work deadline is 6 years. 

2. Built-in memory installments, the data can store up .

3 .Selected high quality materials for steady & Reliable function and appearance

4. Base meter uses the new style hot water meter, wear-resisting, thermostable and easy installation LCD display monitor, high precision ,easy operator. 

5.Electric circuits use the advanced SMT surface to paste install craft, each circuit go through strict testing process (according to industry standard CJ 128-2007 "Heat meter" testing method)
