Product Overview


BOQU BQ-ULF-100W Factory price Fluid velocity analyzer with reply Wall Mounted Ultrasonic Flow Meter

The BOQU handheld ultrasonic flow meter has been upgraded based on the previous handheld ultrasonic flow meter which is still the main product line of the company. The new version retains most of the excellent features and functions of the previous versions: the pulse measurement technology, the ultrasonic igniting and the small-signal receiving circuits, etc. The main improvements are made on the battery supply circuit and on the transmitting circuits. All other circuits are simply integrated into this new version without major modifications, due to the fact that we have already applied the most advanced measurement technologies and attained a more reliable model of the handheld ultrasonic flow meter.
