Madison Company offers several drum level indicator products designed specifically for standard 20, 30 and 55-gallon drums. These level indicators will fit-up directly with standard 3/4" NPT bungs.

Available in low level, high-level and multi-level designs, for both low and high-level indication. The basic level switches require a power source. When configured with an alarm, battery power is on-board.

Optional alarms are available in either a fixed-mount (to the level switch) or a remote-mount design. This option provides both the level switch and the alarm with battery power for ease of use in remote sites where a power source is not readily available.

For those drum applications requiring a non-contact ...

Madison Company offers a complete line of Standard models of advanced ultrasonic level sensors for liquids and solids. These products continue to meet demanding applications in many markets, at competitive prices.

In addition, Madison Company has the engineering capabilities to design these sensors for your specific non-contact level measurement needs, providing unique considerations for materials to be measured, vessel configuration and system interfacing.

The microprocessor-based circuits provide a temperature-compensated signal for improved accuracy. All models have the ability to filter false echoes produced by peripheral obstructions.

Continuous level measurement can be provided in a range of 0.16' to 90' ...

Madison Company’s "Mini Probe" is an addition to the full range of ultrasonic level sensors already offered. Its design is compact, extending just over 2" in height above the tank or drum surface, and it has an operating range of 4" to 6' (0.10 m to 1.8 m).

As with all of our standard Ultrasonic models, the U3M has a PVC housing that allows for an operating temperature range of -40 to 60°C (-40 to 140°F).

The U3M’s microprocessor-based circuits provide a temperature-compensated signal for improved accuracy and the ability to filter false echoes produced by peripheral obstructions. On-board push buttons allow for calibration without the need for software and computers. Optional RS485 communications ...

In addition to the Madison-Omni® configurations featured in Madison’s reed-switch-based continuous level devices, the Madison-Omni® design is available as an ultrasonic sensor for short-range (8" - 48" or 12" - 90") measurement.

There are four models and two standard ranges available with the integrated Madison-Omni® display. This universal display is the same one utilized in reed-switch-based level measurement. It offers user-programmable settings and, in addition to the displayed values, features an LED alarm light.

This non-contact level measurement sensor can be used in various liquids and solids. Level measurement can be displayed in inches or centimeters. As with all ultrasonic devices, you ...

Madison Company offers a series of low-cost radar sensors for continuous tank level measurement. This product series offers a logical extension to the ultrasonic sensor series, where application conditions are in need of non-contact liquid level measurement, and where ultrasonic level measurement is not acceptable.

As with all Madison products, this radar technology can be designed for your specific level measurement needs, providing unique considerations for materials to be measured, vessel configuration and system interface.

These radar level sensors are ideal for reflective liquids that have a foaming surface or vapor conditions beyond ultrasonic wave capabilities.
