M2110 Series Pressure/Flow/Level Digital Intelligent Meter


Meriam's M2110 series intelligent meters are a response to popular demand! It incorporates Meriam's new technology, the new Embedded Pressure Instrument (EPI), while maintaining the original design of the same housing and user interface. With a large display screen, flexible installation (panel, pipeline, or desktop) and power options (24 VDC, battery, or AC), it is an ideal meter for almost any application. The M2110 is equipped with NIST traceable accuracy of +0.05% F.S., unaffected by temperature, at a very reasonable price.

Pressure ranges are now available to measure differential pressure, gauge pressure, compound pressure, and for various gases and liquids. The display can read out in any selectable engineering unit or be scaled to overflow rate or tank level depending on the selected model.

An adjustable damping feature reduces the effects of pulsating pressure. AC-powered units with SPDT relays or 24VDC units with 4-20mA output make the M2110 ideal for numerous control and recording functions. Both models also include additional control and recording functions via RS232C communication.
