Bamo BAMOPHAR 759 Flow Calculator for Open Channels

Description

Bamo BAMOPHAR 759 Flow Calculator for Open Channels is easy on the 4.3″ color touch screen for flow-rate or height of liquid, as well as for totalization. Through a user friendly menu, settings are easy for thresholds, alarms, sampler monitoring and all parameters. Flow Calculator for Open Channels BAMOPHAR 759 converts the input signal directly into flow-rate, through a calculator and using formulas and calibration tables of our Venturi channels (ISO 4359) and our standard V or U channel weirs.

Bamo BAMOPHAR 759 Features:

  • Color touch screen
  • Display of level, flow-rate, daily volume and totalization
  • Flow-rate tables for Venturi and weir plates
  • 1 Input 4-20mA and 1 input Pt 100 Ohm
  • 2 analogue outputs 0/4-20 mA
  • 4 programmable relay outputs; 2 as alarms, 1 for sampler, 1 for pulse output)
  • OPTIONS:
    • RS 422 /J-BUS + LOGGER
    • Extension terminal for a second measurement input

Extension terminal (panel, wall or DIN rail mounting):

  • Allows a second measurement (Turbidity, pH, Conductivity, etc.)
    Data from this blind unit are displayed on the main device
  • Connected to main unit with a 2×2-wire shielded cable
    (Cable length between both devices: max. 500 m)
  • Extension terminal uses the RS 422 and data logger of main unit

Main Features:

  • End-user interface: Color touch screen 4.3”, resolution 480×272 pixels
  • Display of: measurements, flow rate, temperature, height of liquid, daily volume and totalization, status of relays, settings – Configuration keyword protected
  • Flow-rate: (m³/h) – Resolution 0.1 m³/h – Volumes (m³) – Resolution 1 m³
  • Memorized flow-rate tables In memory for Venturi channels, weird plates in V or U
  • Sampler monitoring: S2 Set up on volume (m³)
  • Pulse output: S4 For external counter – 1 pulse/m³
  • Measurement outputs: 0/4-20 mA (max. 600 ?)
  • Options: (RS 422 + Logger): Interface RS422 output, J-BUS link – Binary slave mode – 2400 to 9600 bauds; Data Logger Record of cycle average measurement – 150 000 records max. on memory card.
