Flow alarms

Flow alarms type GIR for Platon NG-LG series
Flow alarm for glass tube flowmeter
Floscan GIR flow alarms use an infra-red beam across the glass tube of a variable flowmeter.

Type FSV4 liquids
Type FSV4 liquids
For pipelines from 1½" to 20", this paddle operated flow switch uses magnetic coupling to transmit the vane movement across a solid metal diaphragm to the electrical switch output. Suitable for general purpose use.

Type FSV6 liquids
Type FSV6 liquids
The Flotect is a paddle operated flow switch for 1/2" to 2" pipelines. Magnetic coupling between the spring loaded vane and the microswitch gives a totally glandless construction, suitable for up to 2000psi liquids.

Type VK
Type VK
The body of the flowswitch is a standard pipe tee, BSP threaded, which contains a paddle type vane. Flow pushes the vane against magnetic forces: when flow exceeds a critical value the magnet actuates a reed switch.

Type LF
Type LF
Liquid low-flow switch for alarm duty on
1/2" or 3/4" pipe. Install with flow direction vertically upwards. Contacts made for high flow, i.e. normal conditions.
