The flow meter / pulse counter AR715

Digital meter for measuring flow and balance, pulse counter, incremental encoder control, dispenser, analogue retransmission output, optional RS485, 4-colour display, panel-type 96x48mm.

Product Description

  • configurable measurement mode:
    • measurement of flow and balance
    • pulse counter
    • incremental encoder (measurement of rotational speed, rate of turn, shifts)
    • dispenser (simultaneous dosing and counting)
    • frequency measurement
    • remote display via RS485, MODBUS-RTU, slave
  • maximum measurement frequency:
    • 10kHz - for a flow, frequency, rotational speed
    • 30kHz - for the counter with PNP output
    • 100kHz - for the counter with NPN output
  • balance capacity: 2x10^9 [units] with sign (-1999999999 ÷ 1999999999), 10 digits when the position of dot is equal to 0
  • universal pulse inputs (IN1, IN2) for flow meters, presence sensors, encoders with outputs:
    • open collector of NPN type
    • open collector of PNP type
    • contact (reed, mechanical)
  • additional inputs:
    • S - start/stop of counting (permission for counting)
    • R - reset of counter/balance
    • B - binary input of the programmable function
  • 2 relay outputs or optionally SSR with programmable operational characteristics
  • analogue output 0/4÷20mA or 0/2÷10V (alarm, retransmission)
  • built-in power supply adapter to power the flowmeters, encoders and other sensors 24V/50mA
  • four-colour LED display with adjustable brightness
  • access to configuration parameters protected by a user password or no password required
  • programming via 4-button membrane keypad or digital interface
  • programmable function button ("F") and binary input for changing the operational modes: keypad lock, unconditional manual mode for outputs, HOLD function for displaying flow measurements, dosing start/stop
  • programmable options for communication, alarms, and other configuration parameters
  • methods for configuring parameters:
    • via membrane keyboard (IP65) located on the front panel of the device;
    • via RS485 port or PRG (AR956/955 programmer) and freeware ARsoft-LOG (Windows 7/8/10), MODBUS-RTU
  • software and programmer allow you to view the measured value and quickly configure single or few sets of parameters previously saved in the computer for re-use, e.g. in other devices of the same type (duplicate configuration)
  • high accuracy and resistance to interference occurring in industrial environments
  • panel housing 96x48 mm, IP65 from the front, IP20 from the connectors
