- MCERTS Approved
Product Options
Overview
The Sitrans LUT400 series are a range of compact, single-point, ultrasonic level controllers suitable for long-range continuous level or volume measurement of liquids, slurries and solids. They are also suitable for open channel flow measurement.
There are three versions available to choose from depending on the application, functionality and level of performance required:
- The SITRANS LUT420 provides level or volume measurement of liquids, slurries and solids. It also benefits from basic pump control functions and logging facilities.
- The SITRANS LUT430 features the same functions as the LUT420 but also benefits from a full suite of advanced pump control and alarm functionality, open channel flow measurement, and basic flow logging.
- The SITRANS LUT440 provides high accuracy OCM. It has all the features of the LUT430, plus a full suite of advanced control functionality, enhanced flow logging capabilities and the industry's best accuracy (+/- 1mm within 3 m).
MCERTS
The SITRANS LUT430 and LUT440 are now MCERTS certified meeting the Environment Agency's performance requirements. View downloads for certificate.
