DM4N

Level Measurement

Float-Tape type Level meters

Digital Transmitters

The DM4N series is a digital data transmitter with a built-in microprocessor.
Installed at tank side, the DM4N series collects and transmits liquid level data in digital signals from tank gauges as well as liquid temperature from sensors inside tanks and status contact signals from valves or others used for loading and unloading operations.
Keeping the compatibility of signals and installation methods with the existing well-established DM4 series the DM4N has enhanced its reliability much more.
