Frequently Asked Questions
What makes the TLG Boiler Type different from a standard gauge?
Its chamber, float and sealing are uprated for high-pressure saturated steam, and the arrangement is engineered to the applicable boiler code — where a standard gauge is built for general tank and vessel duty.
Can a magnetic level indicator be used on a steam boiler?
Yes, for suitable duties and within the applicable boiler code. TOTFLEX engineers the boiler-type unit to the drum's design pressure, temperature and code requirements, and confirms the basis for each order.
Why replace a gauge glass with a magnetic indicator?
A sealed magnetic gauge removes the breakage and scald risk of high-pressure sight glass, stays clearly readable in a hot boiler house, and needs far less maintenance.
Does the boiler-type gauge give a signal to the control room?
It can. A transmitter on the chamber provides a continuous 4–20 mA output alongside the local flag display, complementing the boiler's level controls.
What pressures and temperatures can it handle?
It is engineered to the specific boiler's design pressure and saturation temperature; the exact ratings are set per project and verified against the code.
Does TOTFLEX export boiler-type level indicators worldwide?
Yes — TOTFLEX manufactures them in Turkey and ships them globally with full documentation.
