Remote type vortex flow meter MVF-2901
Marmonix Remote Wall mounted Vortex Flow Meter MVF-2901 is used in numerous branches of industry to measure the volume flow of liquids, gases and steam. Applications in the chemicals and petrochemicals industries, for example, in power generation and heat-supply systems involve widely differing fluids: saturated steam, super-heated steam, compressed air, nitrogen, liquefied gases, flue gases, carbon dioxide, fully decriminalized water, solvents, heat-transfer oils, boiler feed water, condensate, etc.
Remote type vortex flow meter MVF-2901 Features
- Vortex flow meter body is robust and universally applicable for liquids, gases and steam, optimized for steam applications.
- For gases measurement, if the gas temperature and pressure change a lot, pressure and temperature compensation will be a must, vortex flow meter could add temperature and pressure compensation.
- To protect the sensor, vortex flow meter choose embedded sensor, with 4 piezo-electric crystal encapsulated inside the sensor, which is our own patent.
- There are no moving parts, no abrasion, and non -wearing parts inside the vortex flow meter sensor, fully welded SS304 body (SS316 selectable).
- With patented sensor and flow sensor body, vortex flow meter could eliminate drift & vibration influence from great aspect in the working site while compare with other flow meters.
- Apart from electromagnetic flow meter and ultrasonic flow meter could work as flow meter and BTU meter, add the temperature sensor and totalizer, vortex flow meter could also work as BTU meter and measure steam or hot water energy.
- Requires very few power consumption: 24 VDC, 15 Watts maximum;
In gas measurement, vortex flow meter could achieve high accuracy ±0.75%~±1.0% of reading (gas ±1.0%, liquid ±0.75%); which could use in custody transfer, while the metal tube rotameter or orifice plate usually use for process control. - With a variety of signals outputs and selection, such as 4-20mA, pulse with HART or pulse with RS485 are selectable.
- In the electronic device of measuring flow, vortex flow meter is the only one could resist wide temperature range up to highest temperature 350℃, digital flow meter highest process temperature.
