1. Introduction:
Hoffer type HFLG level gauge is a kind of level gauge suitable for liquid medium measurement. HFLG can choose split or integrated. Split typeThe liquid level gauge establishes a wireless communication network through remote communication, and the coverage range can reach 1000 meters. Base stations within close range can use a frequency for 98MHz base station communication bus, or use 4-20mA, Modbus or Profibus-DP transmission anywhere. HFLG can choose IP68.ensor components are suitable for use in wet environments or underground mining.
At present, HFLG type level gauge is widely used in petroleum, petrochemical, chemical, pharmaceutical, paper, food and energy industries. In the process of inspection.And trade handover measurement and other occasions is often used in liquid level measuring instrument. HFLG level gauge has been highly valued by the international level measurement session.
And the majority of users welcome, is the world's more advanced, the most widely used a liquid level measuring instrument.

2. Technical features:
♦HFLG type level gauge has no moving parts, so it has high reliability, long service life and small daily maintenance.
♦ Its liquid level height measurement accuracy is high, good repeatability, can be in a relatively large range ratio range, high accuracy of liquid height direct measurement.
♦HFLG level gauge can measure a wide range of medium types, in addition to the general viscosity of the liquid can be measured, but also can measure a variety of high viscosity liquid. For slurry containing solid phase composition, containing trace amount
Fluids of gas phase composition can also be used under certain conditions.
