Bamophar 759 flow calculator for open channel converts the input signal directly into flowrate, through a calculator and using formulas and calibration tables of our Venturi channels (ISO 4359) and our standard V or U channel weirs.
The reading 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.
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
