Overview
The IMSL submersible level transmitter is ideal for applications requiring continuous submersion in liquids such as water, oil and other non aggressive chemicals. The IMSL offers excellent repeatability, resolution and stability for use in rivers and reservoir measurement. It uses the latest piezo-resistive media isolated silicon sensing technology and stainless steel diaphragm. A 316L stainless steel housing makes this submersible level transmitter the ideal product for repeatable and reliable hydrostatic level measurement. The IMSL is tempearture compensated and calibrated. Each device comes with a traceable serial number and calibration certificate.
