A large float follows the liquid level. a rope attached to it moves over pair of pulleys. Level is indicated by pointer, on 150 mm wide aluminum scale directly or by magnetically isolated external bi-colored Roto-cylinders/follower capsule.
MOC: SS, PP lined
Float & Rope: SS316, PP
Range: Upto 20 Meters
Operational Pressures: Atms. to 1000 mmWC
Operational Temperature: -50 to 300oC Max
Self Centrering float needs no guide wires
Large roller guided pointer
Corrosion resistant modular scales
For Corrosive Applications: PP wetted parts:PP lines aluminum pulley housing with moulded PP Pulley available.
Working: A magnetic float (for side mounted magnetic level indicator) or a magnetic tip (for top mounted magnetic level indicator) moves in a chamber on which the sensor is mounted. Magnetically operated reed switches connected to a string of resistors, sense the level signal. The sensor resistance varies in proportion to level. This is converted into 4 to 20 mA current by the Loop Powered Transmitter. LCD display(optional) locally shows the reading
