Product Description

Welcome to Jiangsu Aice Instrument Technology Co., Ltd., where cutting-edge technology meets unparalleled precision. Discover our innovative solutions and experience excellence in every detail.

Product Description

The Acoustic Doppler Point Flowmeter is an advanced flow detection instrument designed specifically for rivers, open channels, and pipelines. Leveraging state-of-the-art ultrasonic detection technology, this device boasts exceptional measurement accuracy and robust stability. It remains unaffected by environmental variables, eliminates the need for rotating parts, and ensures minimal maintenance. High working reliability makes it the premier choice for both online and portable measurement applications.

Utilizing the Doppler effect, this sensor accurately correlates the frequency difference between transmission and reception with flow velocity. Additionally, it calculates the time difference between ultrasonic transmission and reception to determine liquid levels. Designed to handle special working conditions, it also measures static pressure levels and ambient temperature to correct the actual speed of ultrasonic propagation, delivering precise and reliable measurements every time.

2.1 Installation Instructions
For the installer’s safety and to ensure optimal sensor operation, follow these steps in order:
:
1) Securely mount the meter box and sensor bracket.
2) Insert the meter head into the case, ensuring it’s firmly secured.
3) Install the sensor meticulously.
4) Proceed with the electrical connection carefully.

2.2 Mainframe Installation
Choose between embedded and wall-mounted installation for the mainframe.
1) External dimensions: 176 x 150 x 86mm.

Wall mounting dimensions: 167 x 105mm.
Designed with four quick wall mounting holes. Fix the screws according to the wall mounting points, then hang the product securely.
Note: During probe installation, ensure British line commissioning products are fixed. Protect the instrument from sun and water to extend its service life.

2.3 Sensor Installation
Precautions:
1) Avoid shocking the sensor!
2) Do not loosen the locking wire connector on the sensor during installation to prevent damage.
3) Ensure water does not freeze around the sensor to avoid damage.
Sensor dimensions are as follows:

1) Follow these guidelines when selecting a sensor mounting location:
2) Position the sensor where it will provide representative measurement results.
3) Install the sensor in an easily accessible spot for convenient regular cleaning.
4) Place the sensor in a well-mixed part of the process with no downtime, typically near the sampling point.
5) Install the sensor near a representative process sampling point, within 1.5m (5 feet) for optimal calibration and use. This facilitates accurate comparison of instrument readings with laboratory analysis results. Incorrect sampling is a common source of erroneous readings.

2.4 Sensor Installation Method
The installation of the Doppler Sensor via a mounting bracket, ensuring its immersion within the channel or pipe, is ideal for general open channels, pipelines, and similar scenarios. This method guarantees optimal performance and accuracy in various environments.
For optimal performance, the sensor must be securely installed on the mounting bracket. Under no circumstances should the sensor be suspended in water by the sensor cable alone. Ensure the sensor is submerged to a minimum depth of 30cm below the water surface, or to the typical sampling depth, while avoiding direct exposure to intense light.
1) Selection of Installation Site
Select a location with smooth and steady water flow to achieve precise measurements.
In areas where water flow is irregular or turbulent, the measured flow velocity tends to be erratic and unstable, leading to significant measurement errors.
2) Upstream and Downstream Channel Requirements
Under ideal conditions, select an installation site with an upstream straight channel length of 10 times the channel width, and a downstream straight channel length of 3 times the channel width to ensure accurate measurements.

The longer the straight upstream channel, the better the results. Smooth water flow ensures that the velocity measurements are more accurate to the actual flow. This section should remain free from obstructions such as gates or weirs, ensuring a smooth flow pattern ahead of the sensor and minimizing turbulence.
