APM Analog Panel Meter, 12-24 VDC

Dwyer, APM-201, Series APM Analog Panel Meter, 12-24 VDC, No Relays, 4-20 mA TransmitterMulti-Pump Alternation Control, Open-Channel Flow, Rate and TotalizerThe Series APM has a unique, rugged, NEMA 4X front panel design that makes it nearly impenetrable in typical applications. The weatherproof, UV resistant, large, dual line display allows for more information making it easier to read and even simpler to program. The intensity of the display can be adjusted allowing this meter to be utilized in dark rooms as well as outdoors, due to its sunlight readable display. It features up to eight visual alarm set points to trigger certain events and three function keys which can be programmed to provide direct menu access. with up to four relays available, the APM features latching, nonlatching, sampling, pump alteration control, and a fail-safe action. Offering programmable delay time, this meter prevents recognition of false maximum or minimum reading which may be caused by the start-up or unusual process events. The APM provides three security passwords that restrict modification of programmed settings. This unit has the ability to obtain non-linear input signals and linearize them with simple to use math functions such as square-root extractor, weirs and flumes exponential linearizer, horizontal round tank linearizer or general purpose 32-point linearizer. The APM is a 1/8 DIN digital panel meter specifically designed for displaying flow rate and total from a flow meter with an analog output. The APM is particularly well-suited for flow applications and can be programmed for a wide variety of display configurations. The upper line can display either flow rate, total or grand total, and the lower line can display either flow rate, total, grand total, or engineering units. It is possible to display flow rate and total at the same time, a very unique feature on a 1/8 DIN digital panel meters.FeaturesThree levels of password protectionMath functions for flow & round horizontal tanks32-point linearization, square root or programmable exponentMulti-pump alternation controlRate displayed as units per second, minute, hour, or dayTotal, grand total or non-resettable grand totalTwo or four relays & isolated 4 to 20 mA output optionsExternal 4-relay & digital I/O expansion modulesApprovalsReduction of Hazardous Substance (RoHS)CE ApprovalUL Listed - USNote: Shallow depth meters will not work with this Series.
