The Model 301 Water Level Temperature Sensor is a compact, all-in-one submersible hydrostatic level transmitter that provides fast, continuous, and accurate water level and temperature readings for a wide variety of applications.

The 301 Water Level Temperature Sensor works with digital protocols – MODBUS and SDI-12 – which makes them easy to integrate into your existing SCADA or PLC systems.

The durable water level pressure sensor provides 0.05% FS accuracy with automatically temperature compensated readings and options for absolute and gauged (vented) pressure sensor setups. Factory calibrated to NIST traceable standards.

There are six pressure ranges (5–200 m), with communication cable assemblies available in lengths up to 300 metres. Vented cables contain built-in hydrophobic water-blocking filters (no consumable desiccants).

The Sensor features a slim, robust 22 mm x 192 mm (7/8" x 7.55") 316L stainless steel housing with a removable nose cone for optional use of the 1/4" NPTM threaded connection to attach to pipes/ conduit. Double o-ring seals prevent leaks, and a Faraday cage design protects against power surges and lightning.

PC software utilities make it very straightforward to set up the sensor for different protocols, perform diagnostics, and update sensor firmware if required. Connect to a PC using a USB-A Programming Cable.

With the fastest output rate on the market at 1 second, the Water Level Temperature Sensor is Ideal for measuring hydrostatic liquid levels longterm in industrial, municipal, and environmental applications.
