The MM Series from HMA INSTRUMENTATION is a dedicated monitor permanently hard-wired to a tank/vessel mounted level transmitter, from which it computes mass head or volume for any shape, displaying this digitally in engineering units and vertical bar graph. An alternative version provides for a horizontal six-digit display without bar graph.

All calibration data, output scaling, and switch settings are factory-configured, and contained in a non-volatile memory. If required, the monitor can be site-configured with data entry via front panel function push buttons and internal switches. Typical applications include fuel and water compartments in marine application, stock management of tank farms and warehouses, hydrocarbons chemical, beverage and pharmaceutical storage tanks and process vessels, and full electrical isolation between input/output/power supply making for easy interface with other systems.
