DN50 High Precision Industrial Flow Meter Vortex Steam Flow Meter
Pulse Output
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 MT6000 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. Design & Installation
It is important to install meter,if not installed well, then would
affect precision, use-life and damage.
1． To avoid strong current, high frequency and powerful switch set,
power supply of meter shall be avoided to near by these equipments.
2． To avoid high-Temp & radiation source. if have to install it,
need heat insulation & ventilated measure.
3． To avoid high-Temp & enchant gas, if have to install it, need
ventilated measure.
4． Vortex flow meter shall be avoided to install on shaking part of
pipeline. If have to install on it,shall add clamp device and
vibration pad which located on 2D to enhance shake proof . meter
has better to installed indoors, pay attention to waterproof when
installing meter outdoors,special notice the joint, make cable
conductor to U shape to avoid water get into the amplifier body
Around installing place shall save enough space,so that install
connection line and maintenance routine
