SC250-rotameter with metal tube

SC250 - ротаметр с металлической  трубкой

SC250 series flow meter for liquid media with a metal tube is a fully automated device made from standard parts and provides high accuracy of flow measurement.

Operating principle
The measurement system consists of a calibrated hole and a conical float. Medium flow is directed upward moves the float until it reaches the equilibrium point, which depends on:
- the weight of the float
- the strength of the flow
- the area of the flow environment

Each float position represents the area between the float and the hole. This area corresponds to the expense. The measurement principle itself is known as the variable cross-section principle.

Applications
- Water treatment plants
- Pharmaceutical, chemical and petrochemical industries
- Power plants and nuclear power plants
- Pulp and paper industry
- Food industry
- Heating and cooling circuits
- Saturated steam circulation circuits
- Furnace maintenance and gas burner management
