LT20: Level Transmitter

- วัดระดับของเหลว

- Output 4-20 mA

- Easy Install

            Level Transmitter LT20 is equipment for measuring level of liquid according to pressure theory, at different level will have different pressure also it will generate different Output 4-20 mA. It is mainly measure level of water such as water in tank, well, underground water, level of water in the river and etc.  it is easy installation just drop LT20 until it get to lowest level. In case of measuring liquid is not water calculation would be needed.

            Level Range x Specific Gravity = level range @ 20 mA.

            For Example LT20 is Level Range 10 mH2o measure Ethanol that has Specific Gravity 0.78 @20 mA therefore Ethanol = 10 x 0.78 = 7.812 m.
