Steam vortex flowmeter selection elements inventory

Project Overview

The steam vortex flowmeter has the characteristics of small pressure loss, large measuring range, and high accuracy. When measuring the volume flow rate under working conditions, it is almost not affected by parameters such as fluid density, pressure, temperature, and viscosity. It has high reliability and low maintenance requirements. Small, can operate stably for a long time. At present, steam vortex flowmeters are widely used in flow measurement of steam medium fluids in industrial pipelines. However, it has a wide range of models. In actual selection, you need to pay attention to the following factors.

Element 1: Steam temperature

Steam vortex flowmeter supports medium measurement from -40°C to 350°C. When selecting the model, the transmitter corresponding to the temperature grade should be selected based on the maximum temperature of the medium. Sensor head element, and the maximum working temperature of the medium should be lower than the rated upper limit temperature of the sensor. High-temperature models of 250℃-350℃ are generally equipped with a radiator.

Element 2: Pipe diameter

Conventional steam vortex flowmeter diameters include DN15, DN20, DN25, DN32, DN40, DN50, DN65, DN80, DN100, DN125, DN150, DN200 , DN250, DN300, DN350, DN400, etc. If the actual pipe diameter is larger or smaller than the selected flowmeter diameter, a shrink tube or an expansion tube should be used to reduce the diameter to ensure the correct use of the flow meter.

Element 3: Flow range

When selecting, the common flow rate should be controlled in the middle and upper part of the measurable range of the steam vortex flowmeter (1/1 of the flow range of the steam vortex flowmeter) 2 to 2/3), try to avoid lower limit measurements.

Element 4: Nominal pressure

The nominal pressure of steam vortex flowmeter is generally available in 1.6MPa, 2.5MPa, and 4.0MPa.

Element 5: Accuracy level

The accuracy of steam vortex flowmeters is generally available in level 1.0 and level 1.5.

Element 6: Protection level

The commonly used IP protection levels of steam vortex flowmeters include IP65, IP67, IP68, etc. IP65 represents protection against dust intrusion and water spray, IP67 represents protection against dust intrusion and temporary submersion, and IP68 represents protection against dust intrusion and continuous submersion. The appropriate IP protection level should be selected based on actual working conditions, and explosion-proof vortex flowmeters should be used in flammable and explosive places.

Other selection factors: meter body material, environmental conditions, power supply, output signal, etc.

The above factors can be selected according to actual working conditions.

Steam vortex flowmeter selection factors are rich, making it difficult for non-professionals to make the right choice. The editor suggests that in the actual selection, you can consult professional technicians or contact us for flow meter selection to ensure the accurate and stable operation of the meter.
