AVFM6.1 Standard type
Applicable to any shape of pipe or open channel.
Measurable water level 25.4mm-4.57m.
Measurable flow velocity 0.03-6.2m/sec.
Setting value is protected even after blackout.
Intrinsic safety is available with an optional barrier.
Metal fittings for easy sensor installation is available as an option .
Operating Principles
A flow velocity (Doppler method) and water level (time flight) are consecutively measured through the ultrasonic wave transmitted from the sensor. The flow rate is calculated by setting the pipe diameter and water channel width.
