Steam Vortex Flow Meter

Steam Vortex Flow Meter

Steam vortex flow meter is a flow meter operating with the Karman Vortex principle for the flow rate of steams (saturated steam, superheated steam, etc.). It could be used in an automatic control system as a flow transmitter. With the Pressure and Temperature Compensation, Vortex flowmeters offer an accurate and reliable steam flow measurement.

The same type of flow switch in the flow sensor can be applied to gases as well as liquids such as water and oil. By adjusting the knob in the flow switch, you can monitor the flow of gas, liquid, etc.


The special method of flow sensor integration makes the probe small size, so there is almost no pressure loss to the fluid. In many cases, directly replacing the pressure switch will make the system have better reliability and wider application range.


With the Pressure and Temperature Compensation, the Vortex flow meter can make sure the accuracy of steam flow measurement.

The steam flow meter has high accuracy, and on some occasions where the precision is relatively high, this flow meter is highly recommended;


Convenient steam flow metering helps us work more efficiently. A small steam flow meter can measure the current instantaneous flow in real-time, and can also know the accumulated flow, which is very convenient.


Compared to some poor quality flow meters, steam flow meters are highly stable in performance, which ensures their service life. The Sino-Inst steam flowmeter has a one-year warranty and the flowmeter can be used for 6-8 years. It is durable.

High Temperature and HGigh-velocity Steam

Temperature and pressure are unstable in the steam flow. The temperature-compensated integrated vortex flowmeter also has a temperature sensor that directly measures the temperature of the saturated steam and calculates the pressure to show the mass flow of the saturated steam. The temperature and pressure compensation integrated steam vortex flowmeter has a temperature and pressure sensor.

The gas flow measurement can directly measure the temperature and pressure of the gas medium, thereby indicating the volumetric volume flow of the gas. Automatically correct the nonlinearity of the meter coefficient by software, which can effectively improve the measurement accuracy.

Compressed Air

The Vortex flow meter for compressed air monitors the standard volume flow of compressed air in industrial use. It detects the four process categories flow velocity, volumetric flow quantity, consumed quantity, and medium temperature. The sensor delivers reliable process values even in case of temperature or pressure fluctuations. The high accuracy of the sensor enables the reliable detection of even the smallest quantities or leakages.

What is the steam flow meter?

Steam flow meters are digital flow meters for steam flow measurement. A variety of technologies are suitable for steam flow measurement. Common types are Vortex flow meter. Differential pressure flow meters and portable ultrasonic flow meters work too. Other technologies to measure steam, like Coriolis flow meters. But the price vs the advantages against vortex or DP flowmeters is not justifying the price of a Coriolis flowmeter.

How does a vortex flow meter work?

Vortex flowmeters operate under the vortex shedding principle, where oscillating vortexes occur when a fluid such as water flow past a bluff (as opposed to streamlined) body. The frequency that the vortexes are shed depends on the size and shape of the body. It is ideal for applications where low maintenance costs are important. Industrial size vortex meters are custom built and require appropriate sizing for specific applications.
