Vortex Flow Meters

Vortex flow meters have an obstruction in the path of the flowing media known as a bluff body. As the medium passes by vortices are formed on either side and break away in an alternating pattern. This causes pressure pulsations.  A sensing element picks up the pulsations and converts them into a signal. Suitable for liquid, steam or gas. It is very durable and operates independently of pressure and temperature variations.

    Precession Vortex Flowmeter | LUGB

    Precession Vortex Flowmeter  - Overview

    This flowmeter is able to measure gas flow at low pressure, has multi-signal output and hyposensitivity flow disturbance technology. It combines the functions of gathering flow, temperature and pressure testing, and can carry out the temperature, pressure and compression factor compensation automatically. This is widely used in the measurement of natural gas, coal gasification, liquid gas, light hydrocarbon gas etc. The microprocessor has high reliability and operational precision. This leads to superior performance of flow monitoring in an inline gas pipe measurement.

    Insertion Vortex Flow Meter | LUGB-Insertion

    Insertion Vortex Flow Meter - Overview

    This insertion vortex flow meter measures the volume flow of non-conductive liquids, gases, and saturated and superheated steam. It has no moving parts, eliminating abrasion and wear. It is in a fully welded SS304 body (SS316 selectable). It has a patented sensor and flow sensor body and eliminates drift and vibration influence. It is highly accurate, especially for gas flow. It has a variety of signal outputs and selections such as 4-20mA, pulse with HART or pulse with RS485. When the temperature and pressure change significantly in gas flow measurement the vortex flow meter could add temperature and pressure compensation. The vortex flow meter could also work as a BTU meter and measure steam or hot water energy.  Applications include the chemicals and petrochemical industries. Suitable for use with light oil or any purified water, such as thermal oils, desalinated water, demineralised water, RO water, boiler feed water, condensate water etc.

    Insertion Vortex Flow Meter - Features

    • Measured Medium: Liquid, Gas, Steam
    • Accuracy: 1.0% (Flange), 1.5% (Insertion)
    • Power Supply: 12-24V/DC or 3.6V battery powered
    • Medium Temp: -40℃~+200℃; -40℃~+280℃; 40℃~+350℃
    • Nominal Pressure: 1.6MPa;2.5MPa;4.0MPa;6.4MPa (Other pressure can be customised)
