Vortex Flow Meter DN100 Made in China with RS485 Output
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. Features
- The vortex flowmeter has a simple and firm structure, no moving
parts, and good stability.
- Simple installation and convenient maintenance.
- The measurement range is wide, the ratio is as high as 10:1.
- Compensate the liquid volume as required, and there is no need to
recalibrate the meter coefficient after replacing 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.
