The Pi9911 series of submersible water depth sensors / hydrostatic level sensors are designed for use in rivers, reservoirs, tanks, boreholes, vessels and channels. They are also suitable for the measurement of pressure within submerged pipes and vessels.
The key feature of the Pi9911 water depth sensor is the 5:1 turndown capability. The sensing range is adjusted using DIL switches and fine adjustment potentiometers that are incorporated onto the internal electronics. The water depth sensor's two piece body design allows quick and convenient access to this facility and is sealed by means of an 'O' ring arrangement.
