Display and configuration unit

Display and configuration for modbus level transmitters

4.3 “touch screen display

Up to 3 simultaneous level measurements

Graphical display of the levels

Display indication of the relay status on board

METER, KTU, RPL81 transmitter


VLW90M, a single unit suitable for different applications.Level measurements, difference between levels, open channel flow (hydraulic jump) and pumps control. Different measurement functions directly settable via the keyboard. VLW90M can be connected to ultrasonic sensors and/or to 4÷20mA level transmitters. VLW90M has been developed for the connection to 1 or 2 MODBUS sensors, but it can support up to 8 PTU, METER,RPL81 or KTU units if externally powered. A remarkable note is the data logger on removable pen-drive, which enables the total traceability of the measurements. It is particularly suitable for the Analytical of the flow rate timing in open channel applications.
