Industrial Oil Flow Meter Vortex Flow Meter with Explosion Proof
1. Introduction
LUGBML based on the vonkarman vortex principle, piezoelectric
crystals are used as test elements. It is a new type of vortex
flowmeter for stress detection. It has the advantages of large
measuring range ratio, high precision, small pressure loss, good
versatility of medium, proportional pulse output to flow rate and
convenient connection with computer, because the probe and eddy
current generator of the sensor are installed separately, and the
high temperature resistant piezoelectric crystal does not touch the
instrument. LUGBML series of vortex flowmeter sensors can be used
to detect and measure the flow rate of various gases, liquids and
vapors. Can be used with our ML6000 series vortex Flowmeter. It can
also work with computers and temperature, pressure, density sensors
to form a high-precision mass flow or heat flow detection system.
2. Working Principle
Vortex flowmeter is based on Karman vortex street principle to
measure the volume flow of gas, steam or liquid, volume flow or
mass flow under standard conditions. It is mainly used for the flow
measurement of industrial pipeline medium fluid, such as gas,
liquid, steam and other media.
It is characterized by small pressure loss, large measuring range
and high precision. It is hardly affected by the parameters such as
fluid density, pressure, temperature and viscosity when measuring
the volume flow. There is no movable mechanical parts, so the
reliability is high and the maintenance is small. The instrument
parameters can be stable for a long time. The vortex flowmeter
adopts piezoelectric stress sensor with high reliability, which can
work in the temperature range of - 20 ℃ to + 250 ℃. It has analog
standard signal and digital pulse signal output. It is easy to use
with computer and other digital systems. It is an advanced and
ideal measuring instrument.

4. Design & Installation
It is important to install meter,if not installed well, then would
affect precision, use-life and damage.
1． To avoid strong current, high frequency and powerful switch set,
power supply of meter shall be avoided to near by these equipments.
2． To avoid high-Temp & radiation source. if have to install it,
need heat insulation & ventilated measure.
3． To avoid high-Temp & enchant gas, if have to install it, need
ventilated measure.
4． Vortex flow meter shall be avoided to install on shaking part of
pipeline. If have to install on it,shall add clamp device and
vibration pad which located on 2D to enhance shake proof . meter
has better to installed indoors, pay attention to waterproof when
installing meter outdoors,special notice the joint, make cable
conductor to U shape to avoid water get into the amplifier body
Around installing place shall save enough space,so that install
connection line and maintenance routine.
