Vortex Flow Meter with Fluid Temperature up to 350℃ High
Temperature
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.

5. Design & Installation
It is very important to install the instrument, if not properly
installed, it will affect the accuracy, service life and damage.
1. In order to avoid switch sets with strong power, high frequency
and high power, the meter power supply should be kept away from
these devices.
2. Avoid high temperature and radiation sources. If installation is
required, take heat insulation ventilation measures.
3. In order to avoid high temperature and enchanted gas,
ventilation measures should be taken if installation is required.
4. Vortex flowmeter should not be installed on the part of pipe
shaking. If it must be installed on it, a clamping device and a
vibration pad located in 2D should be added to enhance the shock
resistance. It is better for the instrument to be installed indoors
and outdoors, and pay attention to water proof. Pay special
attention to the joints, make the cable lead u-shaped, so as to
avoid water entering the amplifier body. Enough space should be
saved at the installation place to facilitate the installation of
the connection line and daily maintenance.
