China Flow Metergases Liquids or Steam Indicating Volumetric Mass Flow Meter

We supply various flow meter with best price and quality:
Vortex Flowmeter / Swirl Flowmeter
Working principle:
Vortices occur alternately and regularly to the right and left under a given condition downstream of an object (delta shape bluff body) placed in the flow. This vortex is called Karman vortex, enabling you to know the flowrate from the frequency created. A vortex flowmeter is applicable to liquid, gas, and steam. It has no moving parts and features low pressure loss. It is an easy-to-use flowmeter with high durability and repeatability and is widely adopted in various fields including calorie transactions and calorie control.

What is Vortex Flow Meter?
Vortex flow meter is based on Carmen vortex principle, which adopts piezoelectric crystal as testing components. It is a new kind of stress detecting vortex flow meter. It has the advantages of wide range rate, high accuracy, low pressure loss, good medium generality, pulse signal output proportional to flow, convenient to connect with computer etc. 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.
Vortex flow meter sensor can be used to detect and measure the flow of all kinds of gas, fluid and steam. It can also be used to match with our company's flow totalizer. It also can match with computers and sensors of temperature, pressure, or density to compose high-accuracy mass flow or heat flow detecting and measuring system.

Features of Vortex Flow MeterPiezocrystal inbuilt in bluff body to avoid fluid turbulence caused by external type, no zero drift and high reliabilityNo moving parts, high durabilityConvenient installation and maintenanceSensor not connect with the measured fluids directly, stable performance and long service lifeOutput pulse signal is directly proportional to flow rate, high accuracy and no zero driftWide measuring range, turndown ratio 10:1Low pressure loss, low costFrequency output not affected by the fluid change in physical character and composition, meter factor (K) only considers shape and dimension of eddies. Measurement of volumetric flow can get compensation once it needs. Then no re-calibration meter factor needed if damaged parts be exchangedWide application for air and gas
