Product Description

China Made Brass Portable Ultrasonic Flow Meter Thread Port Connect for Residential Utility Metering/water meter AMR Mbus Lorawan Nb-iot pulse emitter output

Introduction:

For cold water, the numbered drums in a transparent, sealed capsule filled with a special liquid, and equipped with a pressure compensating device and an anti-fogging system for the glass. The sealing of the drums in this way means that this part never comes into contact with the water flowing through the meter and assures a clear and reliable reading of the meter in all conditions. The meter can be installed as horizontal or vertical or any other pose. Has an internal filter. The mechanisms are made from wear-resistant and anti-scaling material. Mechanical transmission not effected by external magnetic fields or ferrous particles in the water. All the characteristics mentioned above make the model meter, which combines the advantages of both the traditional wet dial meters as well as those of dry dial types without the well-known disadvantages of both.

Upon request, the meter can be equipped with a pulse emitter. The rate: 1 pulse per liter.

Features

•  Accurate measurement with conformity to ISO 4064 class C.
•  Volumetric rotary piston principle of measurement;
•  LXHY-15~20 is no location limitation for installation.
•  Accuracy is not to be affected wherever installed at a horizontal, vertical or inclined pipeline;
•  Register is sealed with a specialiquid to keep a clear reading in long term service;
•  Mechanism use of high-quality material to ensure a stable characteristic;

Operating condition:

•  The max water temperature: 50ºC
•  The max admissible water pressure: 1.6mpa.

Error curve:
 

From q_t inclusive up to and including q_s is ±2%;

From q_min inclusive up to but excluding q_t is ±5%.

THE TECHNICAL DATAS CONFORM TO ISO4064 CLASS C STANDARD.

(Note: Innovation for better quality and technology progress might be made without pre-notification)
