Doppler Flow Switch
Control Flow from outside a pipe. Recommended for "difficult liquids" including wastewater, slurries, sludge, chemicals, viscous liquids and abrasives. The Greyline DFS-II is ideal for pump protection…

Open Channel Flow Monitor
Continuously monitor, display, totalize and data log flow through any flume or weir. The OCF 4.0 includes a non-contacting ultrasonic sensor that mounts just 8" (203.2 mm) above the flowing wate…

Monitor flow through open channels, partially full sewer pipes and surcharged pipes without a flume or weir. Ideal for stormwater, combined effluent, raw sewage, irrigation water and streams.

Stingray is a compact, battery-powered logger with an ultrasonic sensor. It data logs level, velocity and water temperature readings for flow monitoring through open channels, partially full sewer pipes and surcharged pip…

Level & Flow Monitor
Use this versatile instrument to continuously measure, display, transmit and control liquid level in storage tanks or pumping stations, or to monitor and totalize Open Channel Flow through any

UL-320 is a clamp on type ultrasonic flow meter. The ultrasonic sensor is mounted to exterior of existing pipe by clamping so that it does not come into contact with fulid flowing thereby making it safe for use in measuri…

The VF-2000 flow sensor body and shedder bar (vortex generator) are molded as one component. Sensor body is made of PPS (Polypylene Sulphide) and is designed to eliminate deposits. A combination of straight flow path and …

Vortex Flow Sensor for Ultra Pure Water
The VF-2200 Flow Sensor is an improved version of the well-received VF-2000 and has a wider flow range than VF-2000. The VF-2200 Flow Sensor is a cost-effective instrument for the …

产生一定的力将开关复位到无流量的位置。当液流冲向叶片时,叶片摆动,改变了磁铁与簧片接触器的相对位置,激发了接触器。一旦液流被中断,叶片回到起始位置,又一次激发接触器。两磁铁的相互排斥提供了磁铁复位所需的力。改用磁力来替代一…
