General information
The series 200 flow sensor is an insertion style flow sensor constructed of metallic and non-metallic materials. These sensors are designed for service in corrosive and non-corrosive liquids.
The series can be installed in pipe sizes of 3” up to 40” (special models up to 120”) and includes a special potted version (IR models) for irrigation applications (enabling direct mounting in the earth).
Measuring principle
Impeller meters
The series feature a six-bladed impeller design with a proprietary, non-magnetic sensing mechanism. The impeller shape coupled with the absence of magnetic drag provides accuracy and repeatability throughout the flow range of the sensors. As the liquid flow turns the impeller, a low impedance square wave signal is transmitted with a frequency proportional to the flow rate.
Applications
Allgemein
In der Kältetechnik gibt es potentielle Anwendungen der Impellerzählertechnologie, z. B. in Kühlanlagen der:
- Pharmazeutischen Industrie
