Product Details

Gas Vortex Flow meter

Application

Air, compressed air, oxygen, nitrogen, coal gas, natural gas, chemical gas, etc.

Feature

1. Without movable parts and adopt simple structure, it is very easy to install and maintain the product.
2. Sensor output is with pulse signal, there is a linear relation between frequency of the signal and actual flow rate
of the medium. The product is with stable performance and no zero drifting, offering pipe and insertion sensor type
options.
3. Wide measurement range, the highest range ratio could reach to 20:1
4. Low pressure loss and consumption.
5. Measure components will not contact with medium, which helped the product to maintain stable performance
and long service life.
6. Assemble with anti-interference circuit and anti-vibration sensors, which could ensure anti-vibration
performance of the product

Introduction

Vortex flowmeter is based on the principle of Karman vortex
research and production, mainly for
industrial pipe flow measurement fluid medium, such as a gas, liquid,
steam and other media. It features a small pressure loss, large
measuring range, high accuracy in the measurement of actual volume
flow is hardly affected by fluid density, pressure, temperature, viscosity
and other parameters. No moving mechanical parts, so high reliability
and low maintenance. Instrument parameters can be long-term stability.
Vortex flowmeter piezoelectric stress sensors, high reliability, can work
within the operating temperature range of -20 ℃ ~ + 250 ℃ for.
Standard analog signals, digital pulse signal output, easily with
computers and other digital systems supporting the use of a more
advanced and ideal measuring instruments.
