The product is according to the principle that the pressure generated by liquids with different specific gravity at different height is linear relationship, to realize accurate measurement and transmission of volume, level height and weight of water, oil and paste-state matters. Widely used in petroleum, ocean, reservoir, river, chemical industry, metallurgy, electric power, scientific research and other enterprises and institutions. The process pressure converts the pressure signal into the electrical signal through the pressure sensor, amplified by differential amplifier and output amplifier, then through conversion of V/A converter, converted to the 4~20mA standard current output signal which has a linearly correspondence relationship with input pressure. Thus showing the size of the liquid level. |
