- U **Non-Volatile Memory** 

The DPF140 Series of flow meters are micro controller based indicators with transmission and pulse outputs. These units are designed to compute and display flow rate and total. The DPF143 has one scaled pulse output and the DPF144 has two. In addition to the scaled pulse output, both models provide an alternative pulse pass-through output with galvanic isolation. The DPF143 is powered by an external DC power source. The DPF144 is a “twowire” or “loop powered” device, meaning that it is powered by the 4 to 20 mA loop circuit itself. 

Pulse and 4 to 20 mA analog outputs can be used to signal external devices, e.g. certain metering pumps and water treatment controls. Alternatively, one or more pulse outputs can be configured as alarm outputs. These flow meters can be password protected to prevent resetting the total or changing configuration settings. 

The DPF140 Series meters are available in wall or panel mount configurations. Wall mounted versions can be converted from wall to meter mount with an adaptor plate. Check with OmegA for compatible meters. Order the DPF144 only if a 4 to 20 mA output signal is a requirement, otherwise the DPF143 offers the most flexibility.
