Global Water level monitoring sensors data loggers and meters
WL16 Water Level Logger
A data logger and submersible pressure transducer combination designed for remote monitoring and recording of water level or pressure data. The water level logger can record over 81,000 readings and has four unique recording options, fast (10 samples per second), programmable interval (1 second to multiple years), logarithmic, and exception.

provides highly accurate water level measurement for a wide variety of applications, including those in severe environments. The submersible pressure transducers have a dynamic temperature compensation system, enabling high accuracy measurements over a wide temperature range. The water level sensor is easily adapted to all dataloggers, telemetry, monitoring equipment, and displays.
WL430 Sewage Lift Station Wastewater Level Sensor
The Sewage Lift Station Wastewater Level Sensor's "Steelcage" design offers the highest reliability in level measurement for severe high solids environments such as sewage, lift stations, storm canals, wet wells and slurry tanks. The wastewater level transmitter system consists of a submersible pressure sensing element cased in a 316L SST housing
WL450 Stainless Steel Water Level Transmitter
Stainless Steel Water Level Transmitter features 316L stainless steel diaphragm and digital temperature compensation and environmentally neutral Hytrel cable for use in test wells, surface water, streams, and reservoirs. The WL450 is available in Stainless Steel or Titanium housing.
WL650 Sonic Water Level Meter
This meter allows you to measure crooked wells, wells with cascading water, partially cased rock wells, wells with submersible pumps, capped or uncapped wells, wells with pipes and wires inside, in fact, you can even measure the length of coiled pipe with the water level meter. As long as the obstructions take up no more than half of the bore area the meter will not suffer any loss of accuracy. The sonic water level meter should only be used on wells under 10 inches in diameter as theaccuracy decreases with larger diameter wells.
WL900 Radar Level Sensor (Non-Contact Level Transmitter)
The WL900 Radar Level Transmitters offer a logical extension to ultrasonic devices, where application conditions are in need of non‐contact liquid level measurement but ultrasonic level transmitter measurement is not acceptable. The WL900 Radar Level Transmitters are ideal for a variety of water and wastewater applications where you have a reflective liquid that has a foaming surface, vapors, or dusty conditions beyond ultrasonic transmitter capabilities. The Radar Level Transmitters are also unaffected by temperature, vacuums, pressure, methane, or CO2.
WA600 Water Level Alarm Sensor
Global Water's Water Level Alarm Sensor (WA600) is a solid-state water sensor for detecting the presence of conductive solutions, such as water spills, water tank levels, and drainage ponds. The water alarm sensor features two stainless steel electrodes that are positioned at a desired point for liquid detection. When fluid is detected, a relay closes in the water level alarm and the signal can be used to sound an audible alarm or close a switch inside a piece of remote monitoring equipment. The relay output is fully isolated and can handle 2 amps of current.

The WA400 is compatible with our WA100 Float Switch and WA600 Water Alarm Sensor for water level alarming, as well as any contact closure.
WA150Tilt Float Switch
The Tilt Float Switch's molded rubber float has an integral three conductor cable and operates on a micro‐switch device that is located inside the rubber float on an anti‐vibration mount. The WA150 Tilt Float Switch includes an adjustable cable weight, which allows it to be suspended from a convenient location above the water rather than having to tie it off at your desired actuation point.
The WA150 Tilt Float Switch's basic operating principle is that as the fluid level rises the rubber float will rise, causing the micro‐switch to tilt and generate a signal that can be used to operate a motor starter, open or close a valve or actuate indicator alarms as required.
WA170 Mechanical Float Switch
The WA170 Mechanical Float Switch offers a reliable low current control for AC and DC applications in potable water, wastewater, and sewage. The internal switching mechanism has sealed gold cross point contacts for reliable low current operation. Common applications include: alarm dialers, pump controllers, SCADA systems, intrinsically safe barriers, solar mapplications, and other low current control and alarm applications.
WA100 Liquid Level Switch
Liquid level float switch used to be suspended in a tank, stilling well or standpipe without the need to tie the float switches off. Ideally suited for sumps, dispeser pans, monitoring wells or double‐ wall tanks where monitoring for leaks is required.
