Metronic MPI-D and MPI-DN devices are multichannel microprocessor measuring instruments dedicated for devices and transmitters communicating on the digital bus (Modbus RTU protocol) and in the HART standard (also in the Multidrop mode). Two PULS type inputs  can measure flow and state. Data are recorded and can be read locally or periodically using a USB mass storage device.

Device can communicate with master system via Ethernet port (Modbus TCP protocol, www server) or via RS-485 (2) port (Modbus RTU and ASCII protocols) and can work in distributed control systems. Device may be configured by the user from the front panel or using commissioning software on PC.
