Why can I take the pressure sensor instead of the liquid level sensor?
In principle, the hydraulic level can be converted to the height of the liquid under the same external conditions.. Therefore, the use of pressure sensors can replace the level sensor ~!To many words, put the P= P GH formula to write up, then what marked the installation position, should be able to get the trust..
Please note that only when pressure level is measured in an open container can the pressure transmitter be used to measure the liquid level in the airtight container and the differential pressure transmitter must be used..In an open container, P= P GH so that h=P/ is p g level can use the variable P, and fixed attribute p g calculated,
P= P GH, P G is proportional to the liquid pressure and liquid level of a constant, pressure sensor installed on the bottom of the tank is under pressure conversion level
