Handheld ultrasonic flow meter
Introduction
Handheld Ultrasonic flow meter incorporates the latest ICs manufactured from the famous semiconductor manufacturers like Philips, Maxim, TI, Win bond, and Xilinx. The hardware features the ease of operation, high accuracy and outstanding reliability, while the software provides a very friendly user interface and much more functions. 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.
