Flow measuring equipment is used to measure the volumetric or mass flow of a substance passing through a section of the pipeline. The devices are used in systems transporting liquids and gases, and less commonly, granular media. Flow meters are purchased by enterprises in the oil, chemical, pharmaceutical, food, engineering, energy, and agricultural industries. The devices are also in demand by companies in the housing and communal services sector.
Depending on the principle of operation, there are several types of devices for measuring flow:
- ultrasonic;
- electromagnetic;
- tachyometric;
- Coriolis;
- vortex;
- pressure difference.
The price of a flow meter depends on its performance characteristics. When choosing a model, it is necessary to take into account the throughput and viscosity of the medium passing through the line. Also, of great importance is the compatibility of the seals and housing parts used with liquid or gas. All flow meters must be operated strictly within the temperature range specified by the manufacturer.
