The INVALCO Model 4200 is a meter-mount or wall-mounted, programmable, battery operated, intrinsically-safe, rate/totalizer suitable for use in NEMA 4X weatherproof areas. As an option, the Model 4200 can be loop powered and supply a 4-20 mA output, or be powered from a 8-35 Vdc supply.
The Model 4200 Rate/Totalizer is designed to accept frequency or pulse inputs from a wide range of flowmeters and to display flowrate and a re-settable total directly in engineering units. Two different versions of the instrument are available: Battery powered version with scaled pulse output. Loop powered version with 4-20mA output. The Model 4200 is fully programmable with K-Factors, linearization of multiple K-factors, decimal point positions, and timebase being programmed via the front panel switches. The instrument is housed in a durable weatherproof polycarbonate enclosure that can be mounted directly on a flowmeter, panel-mounted or wall mounted using a pivoting bracket.
