Series PPM Pulse Panel Meter
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.

Questions
- Question
- Would a UFM-1 and a PPM-100 be a good match to monitor and total domestic water usage for an apartment building? The UFM-1 would be able to be powered from the 24VAC output from the PPM-100, correct? Would the PPM-100 be able to interpret the pulse signal from the UFM-1 and be able to totalize that data for up to 2 weeks on the onboard memory of the PPM-100?
- Answer
- The Model UFM-1 compact ultrasonic flowmeter sends out pulse signals which can be picked up by the Series PPM pulse panel meter. Also, the Series PPM has an isolated 24VDC power supply which the UFM-1 can use. The Series PPM meter has a 6-digit readout which means that it can read up to a million (gallons, liters, m3, etc.). After surpassing the million mark that readout will reset to zero and begin counting again. If needed, the Series PPM can be configured to read continuously, surpassing the millionth mark, by setting the conversion factor on the unit.
