Features:     Benefits: 

The LS-MC is a ultrasonic level transmitter for measurement of liquids in tanks or sumps.  
 
The 4-20mA output represents the distance between the surface of the liquid being detected and the sensor.  
 
The LS-MC has an integral LCD display, 3 push buttons under the lid for security, and just 8 parameters to set 
making it one of the simplest ultrasonic level transmitters to calibrate and use.
