Digital Vortex Flow Meter to Measure High Temperature Steam with
0.6MPa - 4 .0MPa
1. Introduction
LUGBML is based on vonkarman's vortex principle and uses
piezoelectric crystals as the test element. It is a new type of
stress detection vortex flowmeter. It has the advantages of large
turndown ratio, high accuracy, small pressure loss, good medium
versatility, pulse output proportional to flow rate, and convenient
connection with computer. Because the sensor's detection probe and
eddy current generator are installed separately, the high
temperature resistant piezoelectric crystal is not The contacting
instrument has simple structure, good versatility and high
stability. LUGBML series vortex flowmeter sensors can be used to
detect and measure the flow of various gases, liquids and steam. It
can be used with our company's ML6000 series vortex flowmeter. It
can also cooperate with a computer and temperature, pressure, and
density sensors to form a high-precision mass flow or heat flow
detection system.
2. Working Principle
Vortex Flowmeter is a volume Flowmeter which is produced according
to Carmen vortex principle to measure the volume flow rate of gas,
steam or liquid, the volume flow rate of standard condition or the
mass flow rate. Mainly used in industrial pipeline medium fluid
flow measurement, such as gas, liquid, steam and other media.
It is characterized by small pressure loss, large range and high
precision, and is almost unaffected by fluid density, pressure,
temperature, viscosity and other parameters when measuring volume
flow under working conditions. No moving mechanical parts, so high
reliability, small maintenance. Instrument parameters can be stable
for a long time. Vortex Flowmeter adopts piezoelectric stress
sensor with high reliability and can work in the working
temperature range of -20℃~250℃. There are analog standard signals,
but also digital pulse signal output, easy to use with computer and
other digital systems, is a more advanced, ideal measuring
instrument.
