IFM SBT646 2 - 100 l/min Flow Transmitter with Fast Response Time
Brand New
Manufacturer warranty Description
Features:
- Precise detection of flow in pipes
- Suitable for water and glycol solutions
- Very fast (~10 ms) response time
- Robust housing with very high pressure resistance
The SB mechatronic flow meter works on the principle of a spring-supported piston. Flowing liquids lift the piston and the position of the piston is monitored by a magnetic sensor. The spring forces the piston to its original position with decreasing flow and the built-in check valve prevents backflow.
This design means the meter can be installed without regard to inlet/outlet piping requirements. Because a magnetic sensor is detecting the piston position, the response time is ≤ 10 msec. Since the flow is typically relatively stable, there is very little flexing of the spring. The meter has been successfully tested to 10 million cycles without any detectable wear.
