High Temperature Vortex Flowmeter up to 350℃ for Liquid
1. Introduction
LUGBML is based on vonkarman's vortex principle and uses
piezoelectric crystal as the test element. It is a new vortex
flowmeter for stress detection. It has the advantages of large
range ratio, high precision, small pressure loss, good medium
universality, direct ratio of pulse output to flow rate, and easy
connection with computer, etc. Because the probe and vortex
generator of the sensor are installed separately, the high
temperature resistant piezoelectric crystal does not contact the
instrument, and its structure is simple, with good universality and
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 ML6000 series vortex flowmeter of our
company. It can also be combined with computers and temperature,
pressure and density sensors to form a high-precision mass flow or
heat flow detection system.
2. Features
- Vortex flow meter structure is simple and strong, no moving parts,
good stability.
- Easy to install and easy to maintain.
- The measurement range is wide, up to 10:1.
- As required to compensate for the amount of fluid, there is no need
to recalibrate the gauge factor after replacing the attachment

4. Design & Installation
The installation instrument is very important, if the installation
is not good, it will affect the accuracy, service life and damage.
1. to avoid strong, high-frequency, high-power switching groups,
instrument power supply should be avoided close to these equipment.
2. avoid high temperatures and radiation sources. If installation
is required, heat insulation and ventilation measures should be
taken.
3. to avoid high temperature and enchanted gas, ventilation
measures should be taken if installed.
4. eddy current Flowmeter should avoid installation in the pipe
sloshing part. If it must be installed on it, the clamping device
and the vibration pad located at 2 D should be added to strengthen
the shockproof. Instruments are best installed indoors, outdoor
installation attention to waterproof, special attention to the
joint, so that the cable wire into a U shape, to avoid water into
the amplifier body, installation should save enough space, in order
to install the connection line and daily maintenance.
