Differential pressure level gauge used to measure liquid level in high hydrostatic pressure sealed tanks
Thread Content
With a static pressure of 300 kilograms, a measurement height of 800 MM, and a density of 600, can the EJA130 be used to measure the liquid level? It’s mainly the change in pressure that is only a few thousand pascals; it’s uncertain whether it’s possible to detect changes in the liquid level pressure at such high pressures.
Given the medium, pressure is not an issue; a differential pressure range of 48 KPa is also no problem.
The medium is liquid ammonia – is that okay? I’ve never worked with such high pressures before, so I’m not sure
Liquid ammonia is fine; keep the pressure transfer pipe as short as possible and pay attention to insulation.
The EJA130 is a high-static-pressure differential pressure transmitter. There should be no problem.
The instrument selection specifications require that differential pressure measurement should not be used for level detection when the pressure is below 5 Kpa. It is recommended to use buoys or guided wave radar
For low-temperature liquid media, it’s better to use a differential pressure level gauge with a pressure transducer; it will work fine. 0.3 MPa isn’t high, and the differential pressure is sufficient. The key point when putting it into use for resection is to be careful, as unilateral compression can easily damage the surface.
There is no direct relationship between differential pressure and pressure; it is sufficient as long as the transmitter diaphragm can withstand the appropriate pressure. The 130E transmitter has a maximum pressure tolerance of 32 MPa, so it can be used
A differential pressure method is not suitable for measuring liquid level when the pressure is below 5 Kpa. Density changes have a significant impact
