The LMP307 is a submersible level transmitter based on hydrostatic pressure measurement.  When the nose cone is removed there is a flush diaphragm which is ideal for applications with viscous, sludgey media such as waste water treatment, sewage or process applications.  Level ranges from 1mWG through to 200mWG and with optional ATEX and SIL approvals it can be used in hazardous areas.

The submersible level transmitter LMP 307 has been designed for continuous fluid level measurement in water and clean to slightly contaminated media. Housing material is 1.4571 (316Ti); the sensor diaphragm is made of 1.4435 (316L). Standard sealing material is FKM; other materials are available on request. Due to the high-value piezoresistive stainless steel sensor the submersible probe LMP 307 features an excellent linearity and good long term stability. On the basis of the excellent metrological features of the stainless steel sensor it is possible to manufacture the submersible probe with accuracy of 0.05% FSO BFSL. In addition the several cable materials (PVC, PUR and FEP) the customer has the possibility to consider different versions of cable protection. The submersible probe is suited for explosive area (zone 0).
