Handheld Ultrasonic Flow Meter Description

Handheld ultrasonic flow meter uses external clip-on sensing to measure liquid flow, achieving non-contact measurement of liquid flow. The sensor only needs to be installed on the outer wall of the pipe to complete the flow measurement.

During the measurement process, there is no need to destroy the pipeline, no need to stop production, the sensor does not come into contact with the measured medium, and there is no pressure loss. And it also has the characteristics of battery power supply, small size, light weight and easy to carry. It can be said that it has realized the true movable measurement of flow rate and online detection, and is a truly portable ultrasonic flow meter.

Handheld Ultrasonic Flow Meter Application

Handheld ultrasonic flow meters are widely used to measure pure single liquids such as tap water, air conditioning water, and heating hot water. But please note that the pipe must be a hard straight pipe, such as PVC, iron pipe, stainless steel, etc.
The handheld ultrasonic flowmeter can be used for production monitoring, flow calibration, temporary detection, flow inspection, water meter and scale debugging, heating network balance debugging, and energy saving monitoring. It is an essential tool for timely flow detection.

Handheld ultrasonic flow meters can be used for flow detection and measurement of various liquid pipelines, rivers, sluices, etc. include:

Water (hot water, cooling water, drinking water, sea water, etc.);
Petroleum products;
Chemicals, including alcohol, acid, etc.;
Beverage, food and pharmaceutical processors;
Secondary sewage, garbage treatment, etc.;
Pipeline leak detection, inspection, tracking and collection;
It can be used to detect reservoirs, power plants, water pipelines, drainage systems, etc.

Are ultrasonic flow meters accurate?

The measurement accuracy of ultrasonic flowmeter is very high, generally 1%. It is almost free from interference from various parameters of the measured medium. In particular, it can solve the flow measurement problems of highly corrosive, non-conductive, radioactive and flammable and explosive media that cannot be solved by other instruments.

So what causes the ultrasonic flowmeter to measure inaccurately? The reasons for inaccurate measurements are as follows:

The influence of pipeline parameter equipment on the measurement accuracy of ultrasonic flowmeter
Effect of upstream and downstream straight pipe sections on the measurement accuracy of ultrasonic flowmeter
Effect of couplant on measurement accuracy.
The influence of ultrasonic flowmeter sensor installation position on measurement accuracy.

How does a portable ultrasonic flow meter work?

Handheld/portable ultrasonic flow meters measure the flow of liquids using ultrasonic technology. It contains a transmitter and a receiver. The transmitter emits ultrasonic signals into the liquid, and the receiver receives the reflected signals. Based on the propagation time and frequency changes of the ultrasonic signal, the flow rate and flow rate of the liquid can be calculated.

What is the difference between ultrasonic and magnetic flow meter?

Electromagnetic flowmeter and ultrasonic flowmeter are two types of flow meters, which are mainly suitable for measuring the volume flow of fluid in pipelines.

The principles are different:
Electromagnetic flowmeters use Faraday’s electromagnetic induction principle to measure the volume flow of conductive liquids; ultrasonic flowmeters calculate the flow rate and flow rate by measuring the time it takes for ultrasonic waves to propagate in the liquid.

The scope of application is different:
Electromagnetic flowmeter is suitable for liquids with good conductivity, such as water, acid, alkali, etc., and has certain requirements for the conductivity of the liquid. Generally, the conductivity of the medium to be measured is required to be no less than 5uS/cm;
Ultrasonic flow meters are suitable for many types of liquids, including drinking water, food, chemicals, etc., and do not require high conductivity of the liquid.

Measurement accuracy varies:
The measurement accuracy of electromagnetic flowmeter is usually 0.5%;
The measurement accuracy of ultrasonic flowmeter is generally 1.

Different anti-interference capabilities:
The electromagnetic flowmeter has shielded excitation coils during the production process and has good resistance to magnetic field interference;
Ultrasonic flow meters are more sensitive to interference and have weak anti-interference capabilities.

Installation methods are different:
Electromagnetic flowmeters are usually installed inside pipelines, and a suitable installation location needs to be selected to avoid magnetic field interference;
Ultrasonic flow meters are easy to install and can measure non-contactly.

Prices and features vary:
The price of electromagnetic flowmeter is proportional to the pipe diameter, and it has the characteristics of high precision and high repeatability;
Ultrasonic flow meters are relatively low-priced and feature no pressure loss and non-contact measurement.
