Comate - Model VFM60MV -Multivariable Vortex Shedding Flow Meter

Vortex shedding flow meter work principle is to rearching the corresponding relationship between fluid vibration frequency and flow velocity. It measures the flow velocity of fluid by measuring the frequency of sensor output signal. That leaves many vortex meter manuafacturet faced the prolems of vibration, electromagnetic interference and the lower limit of measurement in the development and application of vortex type flowmeter.

Comate understood Vibration then build a new equipment to measure it. Early in 2015, Comate have cooperate with USTC signal processing laboratory and put an unique design method in order to detect the real change of electric charge completely generated by fluids. After that Comate put VFM60MV in factory like compressed air, boiler steam, heating system nad owned a good feedback. The interference solved also makes Comate vortex meter able to measure down to 2m/s velocity than other brand in the marketplace.

To view Comate Multivariable Digital Vortex Type Flowmeters anti-vibration contrast test

• Built-in temp & pressure compensation transmitter
• Patent dual probe design excellent anti-vibration performance
• Measurement limit down to 2m/s wide turndown ratio(for steam: 2~70m/s)
• Compact design integrated temperature & pressure transmitter support high range up to 350°C

• Compressed air, Nitrogen gas monitoring and custody transfer measurement
• Monitoring the compressed air inlet/outlet of the compressor
• Co2, Argon gas, oxygen
• Gas drainage in coal mines
• Measurement Nature gas, biogas process control, and custody transfer

Vortex shedding meter are the most reliable &  accurate measurement innovation technology available & widely accepted across the industries.

Theory of vortex type flow meter according to “Karman vortex”(click here) working theory designed for steam, gas flow, liquid’s volume flow, standard volume flow or mass flow measurement.

VFM60MV Series Multivariable vortex shedding flowmeters incorporate Comate start-of-art technologies. This type of multivariable vortex flowmeter combines temperature and pressure compensation measures the standard flow/mass flow of compressed air, gas directly.

By help of three built-in sensor, a vortex shedding flow velocity, a pressure transmitter, and a temperature sensor, VFM60MV can more accurately measure the mass/standard flow rate of medium though density compensation.

VFM60MV Multivariable Vortex shedding  Flowmeter:

• Extremely high sensitivity, minimum flow rate down to 2m/s with 1:35 super wide turndown ratio
• Patent dual-sensor design and optimized signal processing technology to ensure best anti-vibration
• No moving parts, very small pressure loss
• One vortex flowmeters can measure mass flow, temperature, pressure and density
• Standard output is pulse and 4~20 mA, Hart@4~20mA and RS485 is available
• Password protecting function and self-diagnose function
