SECTION 3
Pr.1.0 APPLICATION SELECTION GUIDE
Miniflex LR can be programmed for Distance measurement, Level measurement, Volume
measurement, Pump control, OCM and Differential measurement. Each application selected
will allow access to only parameters associated with that application.
Distance Measurement
Displays a distance measurement; relay set and reset points can be programmed and a relay
can be programmed for Loss Of Echo indication. A 4-20mA output proportional to the
displayed distance is provided.
Level Measurement
Displays a level; relay set and reset points can be programmed and a relay can be
programmed for Loss Of Echo indication. A 4-20mA output proportional to level is provided.
Volume Measurement
Displays contents, ullage or both contents and ullage. Choose from a variety of vessel shapes
including vertical and horizontal cylinders or a 24-point custom table. Display in Litres,
Gallons, Tons, Tonnes, Kg, m3 or %. Provide a 4-20mA output proportional to contents or
ullage.
Pump Control
For pump control applications; can include pump sequencing, duty standby, pump
maintenance and pump run on.
Open Channel Flow Monitoring (O.C.M.)
For flow measurement, using BS3680 flumes and weirs, Parshall flumes, or custom table for
non-standard devices. Displays flow rate in litres/sec or gallons/sec and totalises in a variety
of units. Provides a pulse output to drive an external totaliser and a 4-20mA output
proportional to level or flow.
Differential Measurement
Uses two transducers switched automatically. The display indicates the difference between
two levels and gives a 4-20mA output proportional to the reading. Relay set and reset points
can be programmed and a relay can be programmed for Loss Of Echo indication.
