Vortex Flow Meter for Oil Industry / Chemical Industry / Metallurgy
/ Heating Power / Paper Making / Spinning
1. Introduction
LUGBML is based on Von Karman’s Vortex Principle, which adopts
piezoelectric crystal as testing components. It is a new kind of
stress detecting vortex flow meter. It has the advantage of wide
range ratio, high accuracy, low pressure loss, good medium
generality, pulse output proportional to flow, convenient to
connect with computer and etc. As the detector probe of sensor and
the vortex generating body are installed separately, and the high
temperature resistant piezoelectric crystal doesn’t contact with
medium, so the instrument is of simple structure, good generality
and high stability.
LUGBML series Vortex Flow Meter sensor can be used to detect and
measure the flow of all kinds of gas, liquid and steam.
LUGBML series Vortex Flow Meter can be used to match with our
company’s ML6000 series Velocity Flowmeter. It can also match with
a computer and sensors of temperature, pressure, or density to
compose high accuracy mass flow or heat flow detecting and
measuring 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.

4. 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.
