  • Contrec 515 series with FA01 application pack is an add or subtract flow computer that is tailored specifically for volume measurement. It can perform either addition or subtraction on two frequency inputs or two analogue inputs.

    The flow computer is suitable for accepting signals directly from flowmeters or for collecting retransmitted signals from other flow computers providing a resultant rate and total. The instrument displays the flow rate and total for each channel as well as a result.

    The frequency input is compatible with a wide range of frequency signals, including millivolt signals, reed switches, Namur proximity switches and pulse trains via its smart front panel program selection. The analogue input can be scaled and have filtering, non-linear correction and cutoff points applied to the signal.

    CALCULATIONS

    For frequency inputs, the calculation of totals is exact as the instrument collects all pulses detected on each channel.

    Channel total = pulses/k-factor

    The flow rates are derived from an accurately measured frequency:

    Channel flow = frequency/k-factor

    For analogue inputs, to derive the flow rate, the analogue input is normalised to a value (A) between 0 and 1.

    Channel flow = (Vfmax – Vfmin) A + Vfmin

    Channel total = (channelflow. Δt)

    The resultant values are then:

    ADD result = channel 1 + channel 2

    SUB result = channel 1 – channel 2

    Product Highlights

    • Programmable for either frequency or analog flow inputs
    • Tailored for volumetric units of measurement
    • Freely assignable alarms for high or low level
    • Allows for non-linear correction
    • Selection of second language and user tags
    • RTC logging with over 1000 entries
    • Infra-red communications port on front panel
    • Pulse width and scaling of pulse output
    • 4-20mA retransmission
    • Selectable protocols on serial ports including Modbus RTU and Printer output
    • Front panel adjustment of 8-24V DC output voltage
    • Backlit Display
    • LCD Backup
