Product Specification

                                              Vortex Flowmeter 6 Inch for Gas / Steam / Water Application

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. Working Principle

Vortex flow meters are volume flow meters that measure the volume flow of gas, steam or liquid, the volume flow of the underlying condition, or the mass flow based on the Carmen Vortex Street principle. It is mainly used for the flow measurement of fluids in industrial pipe media, such as gas, liquid, steam and other media.

It is characterized by small pressure loss, large range and high precision, and is almost unaffected by parameters such as fluid density, pressure, temperature and viscosity when measuring the volume flow of operating conditions. Unmoved mechanical parts, so high reliability and low maintenance. The instrument parameters can be stable for a long time. The vortex flow meter uses a pyrectric stress sensor with high reliability and can operate in the operating temperature range of -20 degrees C to 250 degrees C. There are analog standard signals, but also digital pulse signal output, easy to use with computers and other digital systems, is a relatively advanced, ideal measuring instrument.

6. 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.
