WTL-LUGB temperature and pressure compensation vortex flowmeter

WTL-LUGB temperature and pressure compensation vortex flowmeter

Intelligent Vortex Flow Sensor with Temperature and Pressure Compensation

1、 Product Overview:

The LUGB temperature and pressure compensation intelligent vortex flow sensor integrates temperature, pressure, and flow signals with a new design concept. Through an intelligent digital processor, the three signals are mixed and processed to output a compensated standard flow rate, thereby achieving temperature and pressure compensation for gas and steam. Due to the adoption of an intelligent integrated design concept, the LUGB temperature and pressure compensation intelligent vortex street has the characteristics of compact structure, easy installation, use, and maintenance.

2、 Functional Features

The body also integrates temperature and pressure compensation functions, which can measure the standard volume flow rate or standard mass flow rate of fluids.
Fully intelligent and digital circuit design, capable of automatically compensating for measured fluid density or standard condition volume calculation.
The new digital filtering and correction functions make flow measurement more accurate and reliable.
The battery powered type can work continuously for more than two years without the need for an external power source.
New dot matrix Chinese character LCD display, more convenient to use and operate.
