Principle
Ultrasonic water meter is designed to measure the fluid velocity of liquid within a closed conduit. The transducers are a non-contacting, clamp-on type, which will provide benefits of non- fouling operation and easy installation.

Transit time ultrasonic flow meter send and receive ultrasonic waves between transducers in both the upstream and downstream directions in the pipe. At no flow conditions, it takes the same time to travel upstream and downstream between the transducers. Under flowing conditions, the upstream wave will travel slower and take more time than the (faster) downstream wave. When the fluid moves faster, the difference between the upstream and downstream times increases. The transmitter processes upstream and downstream times to determine the flow rate.

V-method Installation

V-method installation is the moswidely used mode for daily measurement with pipe inner diameters ranging from 15 millimeter to 200 millimeter. It is also called reflective mode or method.

v type

Z-method Installation

Z-method is commonly used when the pipe diameter is between 300 millimeters and 500 millimeters.

W-method Installation

W-method is usually used on plastic pipes with a diameter from 15 millimeters to 100 millimeters

Product introduction and advantages

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.Optimization of the intelligent adaptive signal processing, the user without any adjustment circuit.

Other outstanding features is the signal receiving circuits feature self-adapting performance so as to ensure that the user can easily operate the instrument without any adjustment.
