Liquiphant® M is a Trouble-Free Solution for Universal Liquid Level Detection

Greenwood, Indiana – For pump protection concerning detection of empty pipes and screen applications, rely on the addition to the line of liquid level switches from Endress+Hauser, Inc., Liquiphant® M. This level switch replaces floats in difficult situations, demonstrating its applicability in the water and wastewater industry. Liquiphant® M features proven tuning fork technology that is universal for all liquids. The fork is unaffected by flow, turbulence, bubbles, foam, vibration, bulk solids content, build-up, or fluid properties, and is reliable where other technologies fail. Liquiphant® M can be used anywhere in a tank or pipe since the switch-point is independent of mounting orientation, and the compact size (fork size is 1.5 inches in length) allows mounting to pipes in tight spaces. This creates increased flexibility and easy installation.

This liquid level switch has a factory calibrated switch-point, which requires no calibration or re-calibration resulting in easy, fast installation with minimal training or calibration media/tools. The multiple electronic options allow for easy integration into existing control systems and do not require additional equipment. The self-checking function sounds an alarm in the event of a sensor failure keeping the plant and personnel safe. Liquiphant® M is also effective for empty pipe detection to protect pumps from running dry and resulting in a costly repair or replacement.

Since pioneering the use of tuning fork technology for the detection of point level, more than one million Liquiphant® level switches from Endress+Hauser, Inc. have been successfully installed worldwide. Liquiphant® has become a popular replacement for various types of switches, including capacitance and conductivity probes, and float and gap switches. Today, Endress+Hauser, Inc. supplies more than 75 percent of the world’s liquid level switches, based on tuning fork technology.
