Product details

WESDOM handheld ultrasonic flow meter realizes non-contact measurement of liquid flow. Install the sensor on the outer wall of the pipeline to complete the flow measurement. It has the characteristics of small size. Convenient carrying and accurate measurement.
Handheld Ultrasonic Flow meter Principle Working: Time-transit measurement principle is adopted, the signal transmitted by one flow meter transducer passes through the pipe wall, the medium, and the other side pipe wall, and is received by another flow meter transducer. At the same time, the second transducer also transmits the signal received by the first transducer. The influence of the medium flow rate, there is a time difference, and then the flow value Q can be obtained.

Installation

Wall mount type ultrasonic flow meter installation requirements
The state of the pipeline for measuring the flow will greatly affect the measurement accuracy, the detector installation location should be selected in a place that meets the following conditions:
①It must be ensured that the straight pipe section where the probe is installed is: 10D on the upstream side(D is the pipe diameter), 5D or more on the downstream side, and there must be no factors that disturb the fluid(such as pumps,valves, throttles, etc.) in the 30D on the upstream side. And try to avoid the unevenness and welding position of the pipeline under test.
②The pipeline is always full of liquid, and the fluid should not contain bubbles or other foreign objects. For horizontal pipelines, install the detector within ±45°of the horizontal centerline. Try to choose the horizontal centerline position.
③When install the ultrasonic flow meter, need to input these parameters:  pipe material,pipe wall thickness and pipe diameter. Fulid type, whether it contains impurities,bubbles, and whether the tube is full.

Handheld Ultrasonic Flow Meter

Transducers installation

1.V-method Installation
V-method installation is the most widely used mode for daily measurement with pipe inner diameters ranging from DN15mm ~ DN200mm. It is also called reflective mode or method.

2.Z-method Installation
Z-method is commonly used when the pipe diameter is above DN300mm.

Project case

Flow Meter project – Pakistan

Portable ultrasonic flow meter is used in temporary on-site measurement of different pipelines throughout the project.
