The Contrec 425 Flow Computer can handle a wide range of flow applications where flexibility and high accuracy are required.
While the pulse inputs will interface with most flowmeters.
Contrec 425 can continuously display the Flow Rate or a Resettable Totaling engineering unit on the large six-digit LCD. While a non-resettable Accumulated Total is also displayed with the DISPLAY key is pressed.
The Standard scaled pulse output, suitable for driving remote totalizers and 8 – 24VDC, also provides a power supply for flowmeters and transducers.
High/low flow rate alarms can be output on two form C relays.
An isolated 4-20mA output is available as an option.

RS232 and RS422/485 Communications interface

Communications, included as standard, include both RS232 and RS485 interfaces for communicating with a computer.
Software drivers are also included for some printers and can print a ticket with time and date, a sequential ticket
number, and the resettable and accumulated totals.

Set-Up data is stored in non-volatile memory.

The 425 is initially set up by following a calibration sequence that enables scaling factors, digital filtering, and displays formatting to be set and stored in a non-volatile memory that does not require battery backup.
The instrument will operate from 12 to 28V dc or universal ac mains.

Digital filtering enhances rate accuracy.

Frequency fluctuations caused by pulsating flow through a flow meter often make the rate impossible to read with any precision.

The 425 has a digital filter that will average out these fluctuations and enable the rate to be read to a four-digit accuracy. The degree of filtering is fully programmable, which means that hContrec 425 can obtain highly accurate and stable readings without excessive lag.

Different mounting options are available

The 425 is designed for panel mounting with the facia watertight to IP65 (NEMA 4X) and resistant to most chemicals.

A field enclosure and an explosion-proof are optionally available.
