Why need steam flow meter?

Steam is H2O in the gas condition, we have saturated and super-heated steam. Steam has many applications, the main uses of steam are heating/humidification; vapor can also use in power generation, steam boilers heat reactors, it can be used as a machine drive. A steam engine requires a boiler that boils water to produce high-pressure steam. This boiler can use wood, coal, oil or natural gas or even combustible garbage as a heat source. Common applications of steam are factories that use steam to heat and power plants that use steam to drive turbines. To calculate steam consumption is demanding, and steam flow meters are needed.

Steam flow meter types

Steam flow meters are difficult and complicated to measure, because the temperature of the vapor is relatively high, and some steam pressure is also very large, and the steam also needs temperature and pressure compensation to obtain the mass flow measurement (kg/h, t/h) of the steam. Traditional steam flow meters include differential pressure flow meters ( DP flow metrs), such as orifice plates flow meters, V-cone flow meter,long-radius nozzle. We have several type steam flow meters, such as Coriolis flow meter for vapor, but the cost is not low .At present, vortex flowmeter is a relatively economical and convenient steam flowmeter.

Steam flow meter vortex type

  • Vortex flowmeter principle is Karman vortex principle; it is industrial flow meter for steam, liquid and gas. 
  • Vortex shedding flow meter is a kind of digital steam flow meter with MODBUS, 4-20mA analog output or pulse output. 
  • It has low pressure loss.
  • Within a certain Reynolds number range, the steam measurement result is not affected by steam density, pressure, temperature and viscosity
  • Vortex steam flow meter has no moving parts inside steam flow sensor and easy maintenance
  • It can first measure vapor volumetric flow rate
  • Vortex steam flow meter price starts from $ 300,which is very low price
