Product Details

AM-ULF-H handheld ultrasonic flow meter that has been manufactured by Aumeascon with patent technologies and is equipped with more functions and advanced performance. It has excellent features and functions : 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 handheld ultrasonic flow meter.It employs a patent balanced lower voltage multi-pulse igniting circuit which increases the anti-interference ability magnificently so that the flow meter will work properly even in demanding industrial environments such as those with power frequency transverter working nearby.

Optional Ultrasonic Transducer
