The thermometer manufacturers for you to solve the differential thermometer professional knowledge

Xinjiang some unit engineering in engineer to inquire: unit 50 medium voltage 3. 0 mpa in liquid nitrogen storage tank is equipped with a differential pressure type thermometer, use the carburetor air bath ( Ability = 3000 / hour) Evaporation, average liquid to reduce 0 per minute. 01, the calculated evaporation of 0 per hour. 01 * 60 * 810 = 486 nitrogen gas. Live oxygen experts denied my point of view, said according to the spherical tank only accurate judgment, evaporation pressure, differential pressure type thermometer index, is false, the proportion of liquid will change along with the change of parameters such as pressure, really don't understand the essence of the refs to engineer, please thermometer factory President jiang. 1 sr magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

thermometer factory answer: when other physical conditions of constant pressure curve and the change of liquid level of tank for a period of time is linear, so the so-called experts have this advice and qualitative. 1 sr magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

by differential pressure measurement, and then converted to liquid level height, again into the liquid volume fraction, the links will have additional error, many link is, in fact, there are a lot of unexpected error accident, so I personally think that this kind of measurement is suitable for process control, the trend, and is not suitable for precise measurement. 1 sr magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

one of the more important reason, is you said the gasification process, is a continuous band, affected by other factors such as pressure changes, the ratio is not constant & hellip; … 1 the sr magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer
