MCERTs Class 1 Certified Open Channel Flow Measurement

FlowCERT LITE includes five alarm/control relays plus 4-20mA output, optional data logging. Programming the unit is a simple, menu-driven process.
The special PT100 Class B3 temperature sensor should be mounted in a shaded area near to the path of the level measurement so that the FlowCERT LITE controller can sense and correct for changes in the speed of sound that arise from air temperature changes*.

*NB: in some circumstances direct sunlight/ solar radiation can significantly influence the speed of sound. In applications where this is likely we recommend the use of FlowCERT featuring DUET.
