We are looking to measure liquid level to an accuracy of 1mm. The liquid is not particularly aggressive just tap water with a very low concentration of chlorine. Our range will be around 125mm, we have considered the LMK382 submersible pressure transmitter as a possible solution, would it meet our accuracy requirements?
The LMK382 would be the product we would suggest for measuring over a range of 125 mmH2O. The LMK382 will have an accuracy of 1mmH2O based on the 0.25% FS accuracy of the lowest base range of 400mmH2O range.
