Overview
The Solinst Water Level Temperature Sensor is a compact, all-in-one submersible hydrostatic level transmitter that provides continuous, stable and accurate water level and temperature readings for a wide variety of applications. The water level pressure sensor and temperature sensor are enclosed in a slim, robust 22 mm x 192 mm (7/8" x 7.55") 316L stainless steel housing. Double o-ring seals prevent leaks, and a Faraday cage design protects against power surges and lightning.
Design
Each probe features a removable nose cone for optional use of the 1/4" NPTM threaded connection. The durable water level pressure sensor provides 0.05% FS accuracy with automatic temperature-compensated readings. There are six pressure ranges to choose from (5-200 m), with options for absolute (non-vented) and gauged (vented) pressure sensor setups.
Data Availability
The Water Level Temperature Sensor works with digital and analog protocols – MODBUS, SDI-12, and 4-20mA (add-on Current Loop Adaptor). They are easy to integrate into existing SCADA or PLC systems.Communication cable assemblies are available in lengths up to 300 meters. The cables are easily and securely attached to the sensor using a threaded connection. Simple PC software utilities are used to set up the sensor for the different protocols, perform simple diagnostics, and update sensor firmware if required. A USB-A programming cable is available for connection to the PC.

Solinst Model 301 WLTS: Works Well Under Pressure
From an already successful line of water level and temperature loggers comes the new Water Level Temperature Sensor (WLTS) by Solinst, Inc. Unlike other water level measurement devices offered by Solinst, the WLTS is designed to integrate with 3rd party data loggers in industrial and environmental monitoring systems using digital communication protocols. 
 
 Sensors that can be easily integrated with external devices allow for the addition of stable and continuous water level and temperature measurements to existing monitoring networks. 
 
 While some water level sensors use pressure transducers to determine water level, the WLTS utilizes a hydrostatic level transmitter to record water levels and a platinum resistance temperature detector for temperature compensation.
