Series APM/MPM/PPM
Dual-Line Analog Input Rate/Totalizer applies to level monitoring, pump control, flow rate indication, and process control. Designed for displaying flow rate and total from a flow meter.
1/8 DIN Process and Flow / Rate Totalizers
These 1/8 DIN digital panel meters accept signals from various transmitters and flowmeters and displays them on a six-digit, dual line display in engineering units. These meters will also provide power to the field device and include a NEMA 4X front panel. Free, USB based programmnig sofware is resident on the meter. Options include up to four relays and a 4-20 mA output.
The Series MPM Dual Line Configurable Panel Meter is a general purpose process meter that is field selectable for a 4-20 mA or 0-10 V input signal. It provides 24 VDC to power the transmitter. The dual line display can display the process variable on the upper line and engineering units on the lower line. Or, in dual scale mode, the process variable can be displayed in one units (like height) on the upper display and another (like volume) on the lower display. The meter also has an automatic Round Horizontal Tank function a well as 32 point linearization.
The Series APM Dual Line Configurable Panel Meter and Series PPM Dual Line Configurable Panel Meter are flow / rate totalizers for analog or pulse inputs. The most useful feature of these products is their dual line display which allows rate and total to be displayed at the same time. A non-resetable grand total can also be programmed. Total can be reset either from the front panel or by connecting a remote switch to the F4 terminal at the rear of the meter. The Series APM accepts either a 4-20 mA or 0-10 V input signal and provides the 24 VDC to power the flowmeter. Other features of the APM include square root extraction for DP flow, and programmable exponents for open channel flow.
The Series PPM accepts a pulse input signal and provides either 5, 10 or 24 VDC to power the flowmeter. Adding the 4-20 mA output option converts the pulse into a signal that can be run long distances to a PLC or other device.
FREE USB PROGRAMMING SOFTWARE AND CABLE
The PM Series meters come preloaded with free programming software that connects and installs directly to your PC with a standard USB cable, also provided free with each instrument. This eliminates the need to insert CDs, install drivers, or download software from the internet. The software will allow you to configure, monitor, and datalog a PM Series meter using your PC. Just simply connect the meter to your PC with the USB cable and within seconds you will be programming it.
UNIQUE LEVEL MONITORING CAPABILITIES
The MPM meter is particularly well suited for level monitoring, controlling and alarming applications. For instance, the meter can be programmed to display any two of these parameters on its dual line display: height, volume or percent full. Its six digit display allows it to display volumes up to 999,999 gallons, liters, or any other volume. The meter also has a Round Horizontal Tank function which requires the user to enter only the height and length of a round horizontal tank and the meter will display in volume. Up to four relays are available for alarm and control applications, and the relays can even be programmed to alternate for pump control applications.
