Holykell OEM Handheld Ultrasonic Water Level Sensor with Display

Product profile

The ultrasonic flow meter has been upgraded based on the previous ultrasonic flowmeter 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 ultrasonic flow meter.

Features

* Large-screen LCD                                    * Non-contacting measuring

* Built-in data-logger                                   * Built-in rechargeable battery

* High accuracy measuring                         * Wide measuring range

* Small and light                                          * RS-232 serial interface 

Principle of measurement

The China Wall-Mounted Ultrasonic Flow Meter transit time flowmeter utilizes two transducers that function as both ultrasonic transmitters and receivers. The transducers are clamped on the outside of a closed pipe at a specific distance from each other.  The transducers can be mounted in V-method where the sound transverses the pipe twice, or W-method where the sound transverses the pipe four times, or in Z-method where the transducers are mounted on opposite sides of the pipe and the sound crosses the pipe once. 

This selection of the mounting method depends on pipe and liquid characteristics.  The flow meter operates by alternately transmitting and receiving a frequency modulated burst of sound energy between the two transducers and measuring the transit time that it takes for sound to travel between the two transducers.  The difference in the transit time measured is directly and exactly related to the of the liquid in the pipe, show as follows:

Where

θ is the include angle to the flow direction

M is the travel times of the ultrasonic beam

D is the pipe diameter

Tup is the time for the beam from upstream transducer to the downstream one 

Tdown is the time for the beam from downstream transducer to the upstream one 

ΔT=Tup –Tdown
