Integrated Vortex Flow Meter with Explosion Proof for Liquid
1. Introduction
Based on The vortex principle of VonKarman, LUGBML adopts
piezoelectric crystal as the test element. It is a new type of
vortex flowmeter for stress detection. It has the advantages of
large range ratio, high precision, small pressure loss, good
versatility of the medium, direct ratio of pulse output to flow,
easy to connect with the computer, etc., because the sensor probe
and eddy current generator are installed separately, high
temperature resistant piezoelectric crystal does not contact the
instrument structure is simple, good versatility, high stability.
LUGBML series vortex flowmeter sensors can be used to detect and
measure the flow of various gases, liquids and vapors. It can be
used with our ML6000 series vortex flowmeter. It can also be
combined with computer and temperature, pressure, density sensors
to form a high-precision mass flow or heat flow detection system.
2. Features
- The structure of Vortex Flow Meter is simple and solid, no movable
parts and it is very stable.
- Simple installation and easy maintenance.
- Wide measuring range, the ratio is up to 10:1.
- The volume of fluid is compensated according to requirements, and
the instrument coefficient does not need to be re-calibrated after
the replacement of the accessories.

5. Design & Installation
The installation of the instrument is very important, if the
installation is not good, it will affect the accuracy, service life
and damage.
1. In order to avoid high-power, high-frequency, high-power switch
groups, instrument power supplies should be avoided near these
devices.
2. Avoid high temperatures and radiation sources. If installation
is required, thermal insulation and ventilation measures should be
taken.
3. In order to avoid high temperature and enchanted gas,
ventilation measures should be taken if installation is needed.
4. The eddy current flowmeter should not be installed in the
sloshing part of the pipe. If it must be installed on it, a
clamping device and a vibration pad located in 2D should be added
to enhance shock resistance. It is best to install the instrument
indoors, pay attention to waterproof during outdoor installation,
and pay special attention to the joint to make the cable wire
U-shaped, so as to prevent water from entering the amplifier body,
and enough space should be saved at the installation place for
installation and routine maintenance.
