Technical Overview
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.

    Conformity EN50081-1 & EN50082-2 Country of origin The products referred to in this data sheet meet the requirements of EU Directive 2004/108/EC Tel: E-mail: Web: +44 (0) 1732 861200 - sales@sontay.com - www.sontay.com © 2012 Sontay Limited. All rights reserved...
  • Page 3: Installation

    Shield the LS-MC from direct sunlight. If used with a liquid where foaming could occur, locate the LS-MC over an area of clear liquid. Failure to comply will result in a reduced size of the return echo, thus an incorrect reading.
  • Page 4: General Information

    Power Up On power up, the LS-MC will take a few seconds to initialise, then the display will run through a set-up routine, showing a full set of figure eight’s, then the software revision and finally a full set of zeros whilst the microprocessor identifies the correct return echo and confirms this repeats enough to be acceptable.
  • Page 5: Connections & Dimensions

    LS-MC display is in distance mode. You can now quickly check correct operation against a manual measurement if required. Tip: A feature of the LS-MC useful at this stage is that it can be used as an electronic tape measure. With an empty tank or vessel, the LS-MC will read the distance to the bottom of the tank.
  • Page 6 The 4mA level may be set above or below the 20mA level to suit the monitoring or control equipment. If you wish to set the 4 and 20mA levels by ranging the LS-MC to a fixed target, such as the level in the tank at any particular time, skip ...
  • Page 7 Selecting the output current output on alarm condition: The LS-MC will signal an alarm condition in the event that the target echo is lost for a period of 10s or more. The user can select what action the current output will take in this case.
  • Page 8 To store a new false echo, press the blue button  for greater than 5s. Note : If there are already 2 false echoes stored (Lrn2) then the LS-MC will not allow the user to store another echo until the memory is cleared.
  • Page 9 Power Failure: All parameters are held in E² PROM memory, so in the event of a power failure or disconnection from the power supply the LS-MC will remember all of its last parameter values and will resume correct operation once power is restored.
