No packing gland, diaphragm, float, bearing, bellows or other troublesome pressure seal is used in the Dynatrol level switch design. This unique design provides rugged construction yet a sensitive transmission of vibration energy through a rigid, all-welded pressure seal. (read more)

The 9830-ILA Interstitial Leak Alarm monitors the dry space within a double walled tank. The flexible sensing probe is mounted into the interstitial space so that the probe tip is at the tank bottom.

Any leak of liquid through either wall into the probe space will initiate the alarm. (read more)

Madison Company recently upgraded its Model M3326 subminiature liquid level switch. The switch's specific gravity has been lowered to 0.6, making it suitable for use in more liquids than previously. By introducing a new welded joint, these hollow floats are 100% pressure tested to ensure the 50 psig published specification is exceeded without leaking. (read more)

MTS Systems Corp. Sensors Division has developed a new display meter to work with the Level Plus® MG transmitter with Modbus interface. The meter was developed as a Side Tank Indicator (STI) for storage tanks with the ability to interface via Modbus and display tank levels in feet, inches and 16ths of an inch. (read more)
