TLG Valve Magnetic Level Indicator
A magnetic level indicator with integral isolation valves — the bypass chamber can be shut off and drained for inspection or float maintenance without taking the vessel out of service, in stainless-steel construction with no power required.

Frequently Asked Questions
Why choose the valve version?
Its integral isolation and drain valves let you take the indicator out of service, clean or repair it and put it back — without stopping or draining the vessel.
What valves are fitted?
Isolation valves at the process connections plus a drain valve at the chamber base; materials matched to the body specification.
What are the ratings?
PN10 and up to about 150 °C as standard; other ratings on request as engineered builds.
Does maintenance require special tools?
No — close the isolation valves, drain the chamber and unbolt it like any flanged spool.
Can it carry a transmitter and contacts?
Yes — external transmitters and magnetic switch contacts fit exactly as on the standard TLG.
Which materials are available?
304 stainless standard, 316 stainless optional; valve trim to suit the medium.
