[Daily Question 20090325] Liquid level measurement method of high-pressure vessels
Thread Content
There are many high-temperature and high-pressure containers in chemical plants, such as the liquid level of the condensation tower of the synthesis tower, the liquid level of the urea synthesis tower, etc. The liquid level measurements include differential pressure measurement, isotope measurement, radar level measurement, etc. So what measurement methods have you adopted in these high-pressure containers? Reply format "name: Measurement method, measuring device” e.g.: Heta condensation tower liquid level: Differential pressure method, using high static pressure EJA transmitter to measure urea synthesis tower: Float measurement
Liquid level of hot high-temperature separation tank and cold high-efficiency separation tank of coal tar hydrogenation unit: High static pressure 3051 double flange intelligent transmitter, high pressure float, high pressure float switch, high pressure magnetic flap level gauge (with alarm output)
Drum level: 1. Double chamber balancing vessel method, differential pressure EJA transmitter measurement 2. Float measurement 3. Guided wave radar level meter measurement 4. Radio frequency admittance level meter measurement
Methanol scrubber liquid level: capacitive level meter Methanol separator liquid level: capacitive level meter
Fermentation tank: Double flange level transmitter.
Ammonia synthesis tower: Capacitive level meter
Differential pressure method to measure boiler drum water level Radio frequency admittance level meter to measure drum water level
Wax oil hydrogenation hot high score and cold high score: Double flange differential pressure level gauge. Hot Gaofen uses a total of 4 double-flange differential pressure level gauges, a set of three-to-two interlocking and a liquid level control, without adding local. I have also seen double flanges and floats used together~~~
