Boiler drum level gauge
Thread Content
I’m seeking advice: what types of level gauges are currently in use for the steam drums of mature boilers, both for on-site use and for remote monitoring? In the past, on-site gauges were double-color glass panels, but the fluorescent lights inside them failed very frequently. For long-distance transmission, differential pressure is used, but there is always drift. Are there any better types of level gauges available now? Is there a better way to handle this to make the level gauge more reliable?
Fluorescent lights won’t do; you can opt for LEDs instead. For differential pressure sensors, choose a reputable manufacturer – I use EJA models; after all, for such critical applications, it’s essential to use high-quality products, no discussion possible.
Choose high-temperature resistant magnetic flap valves; for magnetostrictive types (the transmitter part does not require insulation). Use pressure tapping tubes for differential pressure applications, and add condensation tubes if necessary. Identify the real problem and resolve it
Level gauges used in boiler drum systems generally employ differential pressure transmitters with dual-chamber balance vessels； It is mature and stable; any drift indicates problems with the product quality.
Akrein’s electric contact level gauge is said to require no maintenance for over a decade – worth giving it a try
I’ve been using a domestically produced high-temperature resistant magnetic flap level gauge, and it’s worked fine for several years; it’s just the plastic of the outer flaps that has aged, while the transmitter is still in good condition
Outer connection tube guided-wave radar level gauge
An external measuring cylinder is used to install a high-temperature contact-type guided-wave radar. If the pressure and temperature are too high, a model with steam compensation can also be chosen.
1. The on-site gauges are generally glass plate level gauges with lights; our factory also uses them. The glass plates have broken many times, but the lights rarely fail. /2. For remote transmission meters, a double-chamber balanced container along with a differential pressure transmitter is generally used. 3. Add another electrode-type level gauge.
