Contrec 505-LM01 Level Monitor Product Highlights

  • Contrec 505-LM01 and measures the level of product in a single tank.
  • The Level Monitor uses the 4-20mA signal from a wide range of level sensors, including pressure transmitters, ultrasonic sensors, and capacitance probes.
  • The level monitor provides a 20 point strapping table and product density for the level to volume and volume to mass conversions.
  • The instrument can display Volume, Percentage Full, and Mass as well as Level.
  • Relay alarms are freely assignable as high or low alarms and an open collector output is provided for programmable level control.
  • A sub-menu gives full details of alarm status and can offer direct access to change the alarm setpoints.
  • The Level Monitor also has density correction available for pressure level sensors to cater for a deviation in product density.


  • Calculations are based on the analog input signal representing the product level in the tank.

level = (Lmax – Lmin) x A + L min

volume = (Vmax – Vmin) ´ A* x V

min mass = volume x density


A = normalized input signal with density correction.

A* = A for linear tanks.

A* = f(A) for non-linear tanks.

f(A) = level to volume normalised strapping table.
