Whether monitoring drinking water from the source or treating wastewater before it can be released into the ecosystem, managing water resources involves multiple highly complex processes.

Water Level Monitoring

MadgeTech data loggers can accurately monitor and record water level and temperature over time in harsh, difficult environments to assist in compliance with standards enforced by the Environmental Protection Agency and National Primary Drinking Water Regulations.

Submersible Water Level & Temperature Data Logger

The Level1000 is a rugged, submersible, battery powered, stand alone water level and temperature data logger. Its stainless steel enclosure makes it perfect for use in lakes and streams. This is an all-in-one, compact, portable, easy-to-use device that will measure and record data for up to 16,383 measurements. The storage medium is non-volatile solid state memory, providing maximum data security, even if the battery becomes discharged. The device can be started and stopped directly from your computer, and its small size allows it to fit almost anywhere. The Level1000 data logger makes data retrieval quick and easy. Simply plug it into an empty COM or USB port and our user-friendly software does the rest. Data can be displayed in pressure measurements such as feet, inches, meters, centimeters, millimeters or PSI.


Water Temperature Monitoring

The temperature of wastewater is a major concern because when temperature levels are too high, it can have an impact on the microorganisms in the activated sludge system. The maximum temperature of the wastewater entering a biological reactor should
be less than 35 °C (95 °F). Any higher temperatures will damage the biological system in the water.

Submersible Temperature Data Logger

The HiTemp140 series data loggers are MadgeTech’s solution for precise temperature monitoring. These data loggers can indefinitely withstand temperatures of up to 140 °C (284 °F) and have an accuracy of ±0.1 °C (±0.18 °F). The HiTemp140 features a rigid external
RTD probe capable of measuring extended temperatures, up to 260 °C (500 °F). Varied probe lengths are available up to 7 inches to best fit user needs.

Submersible, Miniature Temperature Data Logger

The MicroTemp is a miniature, submersible, self-contained temperature data logger. Only 2.6 inch (66 mm) tall and 0.7 inch (18 mm) in diameter, this data logger can easily fit into the smallest spaces. Don’t let the diminutive size fool you — this is an industrial grade instrument which boasts an accuracy specification of ±0.5 °C and will operate in temperatures from –40 °C to +80 °C (-40 °F to +176 °F).

Ambient Temperature Data Logger

For many applications that require the monitoring of ambient temperature, the Temp101A is the ideal solution. The Temp101A can measure ambient temperature from -40 °C to 80 °C. This compact device can be placed virtually anywhere to provide an accurate temperature record of the environment. Use several Temp101A’s to capture a thorough mapping of large facilities.


Water Pressure Monitoring

Maintaining correct pressure is necessary to guarantee that water treatment systems are operating as intended. Low pressure may be indicative of problems within the system that lead to sluggish operation while higher-than desired pressures can be damaging to
sensitive equipment. MadgeTech manufactures several data loggers that carefully monitor pressure throughout water treatment to ensure process efficacy and protect system integrity.

Differential Pressure & Temperature Data Logger 

The PRTemp1000D is a rugged, submersible data logger that records ambient temperature and differential pressure. The device is designed
to record over long periods of time at the user selected reading rate and has a pressure accuracy of ±.25 % over the Full Scale Range, making the device extremely accurate. The stainless steel enclosure allows it to withstand harsh environments and the flexible cable is
equipped with dual 0.25 inch NPT connections for easy installation. 

Pressure (Transient) & Temperature Data Logger

The PR1000 is a pressure and temperature data logger that accurately records data at user programmable reading rates, over long periods of time. The device can be deployed in the field to record data for weeks or even months based on the user selected reading rate. The rugged stainless steel design allows it to be placed in harsh environments which makes it well suited for steam pressure systems. The PR1000 comes standard with a ¼ inch NPT fitting, which allows it to be connected to almost any pressure adapter.

The PR1000 can also monitor and record transient pressure through software configuration of user defined trigger thresholds and time periods. The logger can be configured to record measurements at rates as fast as 128Hz or as slow as once every 24 hours. The non-volatile memory has a capacity of over 1 million readings.

pH Monitoring

Whether treating drinking water for human consumption or preparing wastewater to be released back into the environment, monitoring pH is
one of the most important aspects of the treatment process. Monitoring the pH of drinking water is crucial because acidic (low pH) water will
leach metal from pipes, causing health risks and damaging infrastructure while basic (high pH) water often has an off-putting taste. In wastewater applications, pH adjustment helps remove heavy metals and other dangerous toxins from the water. To support these processes and more, MadgeTech offers user-friendly pH logging solutions.

pH Data Logger

The pHTemp2000 is a pressure data logger equipped with an LCD screen. The 8 button keypad and large LCD provide convenient access to current data and recorder setup. Available on-screen data include: statistics (min, max and average), recording status (start, stop and recording rate) and calibration information (data calibrated, date for recalibration). The LCD also displays a graph of the last 100 readings to
show data trends.

This rugged, splash-proof (IP65) device has one of the largest memory capacities of any similar data recorder on the market, logging up to
262,143 readings. The non-volatile memory will retain recorded data, even when battery power is lost.


4-20mA Output

MadgeTech’s process data loggers are ideal for measuring and recording 4-20 mA output from wastewater instrumentation, such as flow meters. The devices are engineered for accuracy and flexibility unequaled in the 4-20 mA loop sensor and control industry. MadgeTech loggers can be inserted almost anywhere because they add very little resistance to the loop (10 Ω typical). Additionally, customized Engineering Units can be defined to map the measured data to almost any unit imaginable.

Low Level DC Current Data Logger

Flow rate can be recorded for analysis and record keeping, which aids in accountability reports for applications such as wastewater
monitoring, storm water studies, stream flow recording and irrigation channel research. The Process101A data logger, used to record flow rates, is simply connected to a flow meter, then programmed to start and deployed in the field.
