Clamp Type Vortex Flowmeter Low Flow Rate with LCD Display
1. Introduction
LUGBML is based on vonkarman's vortex principle and uses pyelectron
crystals as a test element. It is a new type of stress detection
vortex street flow meter. It has the advantages of large range
ratio, high precision, small pressure loss, good media versatility,
pulse output and flow ratio, easy to connect with the computer,
because the sensor probe and vortex generator are installed
separately, high temperature-resistant die-electric crystals do not
touch the instrument simple structure, good versatility, high
stability. The LUGBML series of vortex street flow meter sensors
can be used to detect and measure the flow of a wide range of
gases, liquids and vapors. Can be used with my company ML6000
series vortex street flow meters. It can also be combined with
computers and temperature, pressure, density sensors to form a
high-precision mass flow or heat flow detection system.
2. Features
- Vortex flowmeter has simple and firm structure, no moving parts and
good stability.
- Simple installation and convenient maintenance.
- The measuring range is wide, and the ratio is as high as 10:1.
- Compensate the fluid volume as required, and do not need to
recalibrate the instrument coefficient after replacing accessories.

5. Design & Installation
It is very important to install the instrument. If it is not
installed well, it will affect the accuracy, service life and
damage.
1. In order to avoid high-voltage, high-frequency and high-power
switch groups, the instrument power supply should be avoided close
to these devices.
2. Avoid high temperature and radiation sources. If installation is
required, heat insulation and ventilation measures shall be taken.
3. To avoid high temperature and enchanted gas, ventilation
measures should be taken if installation is required.
4. Vortex flowmeter should be avoided to be installed in the
shaking part of pipeline. If it must be installed on it, the
clamping device and vibration pad located in 2D should be added to
strengthen the shock resistance. It is best to install the
instrument indoors, pay attention to waterproof when installing
outdoors, pay special attention to the joint, and make the cable
lead into U-shape to avoid water entering the amplifier body. The
installation place should save enough space for installation of
connecting wires and daily maintenance.
