Dinel FCU-400 Flow Control is used for measuring and displaying the volume flow rate in open channels and drains. The unit forms an assembly with ultrasonic level meter ULM-53 with RS485/Modbus RTU communication output where the power supply for the indicators is provided directly from the unit with an output voltage of 24V DC.

The unit can measure immediate flow rates in up to 4 channels simultaneously. The unit is integrated into the instrument box intended for wall mounting. The connection terminal block is positioned inside of the bottom part of the unit. There are four keys used for the setting of all functions on the front panel. The units can be equipped with either two or four relay outputs. They also include RS485/Modbus RTU – Master communication interface for connection of indicators and RS 485/Modbus RTU – Slave interface for communication with the master.

There is a USB input for transmission of the archived data from the unit to a flash disc or for loading of level height conversion table to the unit memory on the face panel. The customer can also select the webserver. The binary input is in the basic configuration. Individual types can be ordered in two power supply versions
