Product Description

Welcome to Jiangsu Aice Instrument Technology Co., Ltd.

Product Description

 

The Acoustic Doppler Point Flowmeter is a flow detection instrument for rivers, open channels and pipelines. It adopts ultrasonic detection technology, with high measurement accuracy, high stability, low influence by environmental factors, no rotating parts, low maintenance frequency and high working reliability, and is the product of choice for online and portable measurement.

Doppler effect, the frequency difference between transmission and reception and flow velocity to establish a relationship, the time difference between ultrasonic transmission and reception and liquid level to establish a relationship, static pressure level for special working conditions, ambient temperature measurement for correction of the actual speed of ultrasonic propagation.

Installation Instructions

 

Doppler effect, the frequency difference between transmission and reception and flow velocity to establish a relationship, the time difference between ultrasonic transmission and reception and liquid level to establish a relationship, static pressure level for special working conditions, ambient temperature measurement for correction of the actual speed of ultrasonic propagation.
1.1.2 Characteristics
Industrial stainless steel and industrial plastic material, waterproof, anti-corrosion, strong and durable
No wearing parts, less maintenance and low cost of use
High resolution, high measurement accuracy
The service life of the sensor is more than 5 years
Not afraid of the interference of chemical reagents, liquid viscosity and other factors
18-key keypad operation, Chinese and English menus
4~20mA isolated current output
Isolated RS485 (Modbus RTU) communication interface
Upper and lower limit alarm function relay output

2.1 Installation instructions
To ensure the safety of the installer and the proper operation of the sensor, please install in the following order:
1) Mount the meter box and sensor bracket.
2) Fit the meter head into the meter case and secure it.
3) Mounting the sensor.
4) Electrical connection.

2.2 Mainframe installation
The mainframe has two types of installation, embedded and wall-mounted.
1) Mainframe external dimensions 176 x 150 x 86mm.


Wall mounting dimensions 167 x 105mm
The product is designed with four quick wall mounting holes, simply fix the screws in accordance with the wall mounting fixing points and then hang the static product on it.
Note: Probe installation when the British line commissioning products in fixed. In order to extend the service life of the instrument, the instrument should be well protected from the sun and water.

2.3 Sensor installation
Precautions:
1)Do not shock the sensor!
2)Do not unscrew the locking wire connector on the sensor when it is installed, as this may cause damage to the sensor!
3)When the sensor is in water, make sure that the water does not freeze, otherwise the sensor may be damaged!
Sensor dimensions as shown:

1) The following criteria need to be followed when selecting a sensor mounting location.
2) The sensor should be mounted at the appropriate location in the process to ensure that representative measurement results are obtained.
3) The sensor should be installed in an easily accessible location to facilitate regular cleaning of the sensor.
4) The sensor should be installed in a location where the process is well mixed and where there is no downtime, which is usually where the sampling point is located.
5) The sensor should be installed near a representative process sampling point, which should be easy for the operator to perform the sampling operation, and the distance between the sensor and the sampling point should not exceed a maximum of 1.5m (5 feet). During calibration and in subsequent use, it is necessary to sample the process to compare instrument readings with laboratory analysis results. Improper sampling operations are a common cause of erroneous comparison results.

2.4 Sensor installation method
The installation method of immersing the sensor in the channel or pipe through the mounting bracket is suitable for general open channels, pipelines and other occasions.
The sensor must be installed on the mounting bracket. Never hang the sensor in the water with the sensor cable. The sensor should be immersed to a depth of not less than 30cm below the water surface, or to the depth normally reached when sampling, and avoid direct exposure to strong light.
1) Choice of installation site
Choose a place where the water flow is smooth to measure.
Where the water flow is not smooth, in most cases turbulent, the flow velocity measured under turbulent conditions is jumpy and unstable, and the error will be large.
2) Requirements for upstream and downstream channels
Under ideal conditions, the flowmeter installation site upstream of the channel width of 10 times the straight channel, downstream of 3 times the straight channel.

The longer the length of the straight upstream channel the better, the smoother the flow and the closer the velocity measurement will be to the actual flow. And this section should not have any obstructions, such as: gates, weirs, etc., to ensure that the front of the sensor flow pattern is smooth and turbulence-free.
