The differential pressure transmitter gives inaccurate readings for the liquid level of liquefied petroleum gas.

Is the differential pressure transmitter suitable for LPG level measurement?
Are they large spherical tanks in the tank farm or process storage tanks? We use radar level gauges for these spherical tanks. In terms of technology, it is basically a double-flange differential pressure type.
Servo and radar applications are quite common.
Horizontal raw material storage tank, diameter 3 meters, capacity 60 cubic meters
For LPG level measurement, a dual-flange differential pressure transmitter is the best choice; using a differential pressure transmitter with a dual-chamber balance does not provide very stable results.
The radar level gauges we use for our isobutane horizontal tanks also utilize radar technology; those used for coking liquefied gas do as well, but they haven’t been put into use yet, so it’s not known how effective they will be. If the radar units aren’t of high quality, liquefied gas can form mist, which leads to signal loss. Double-flange level gauges should work fine in such cases
What we use here is a differential pressure transmitter combined with dual-chamber pressure balancing
Can a differential pressure transmitter with dual-chamber pressure balancing be used?
It should work, I haven’t used it before. I don’t know how stable it is
