The Series PPM 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
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 PPM features latching, non-latching, 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 PPM 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 a general purpose 32-point
linearizer. Choose from RS-232, RS-422/485 serial communication options
or any available expansion modules, accessories, and enclosures.
The PPM displays flow rate and total simultaneously, with a programmable
relay and 4 to 20 mA option for flow rate or flow total. The PPM is a
1/8 DIN digital panel meter specifically designed for displaying flow
rate and total from a pulsed input provided by open collector, NPN, PNP,
TTL, switch contact, sine wave, or square wave.
Note: Shallow depth meters will not work with this Series.
