summary:

The HLS series ultrasonic flowmeter adopts the principle of time difference method. Accurate measurement, easy to use, widely used in industries such as tap water, sewage treatment, petrochemicals, power plants, refrigeration, etc. When an ultrasonic beam propagates in a liquid, the flow of the liquid will cause a slight change in propagation time, and the change in propagation time is proportional to the flow velocity of the liquid.

characteristic:

1. high precision measurement

Accuracy up to 1%

2. Large measurement range

By selecting different types of sensors, it is possible to measure the flow rate of pipelines with diameters ranging from DN15 to DN800

3. high reliability

Adopting low-voltage and multi pulse transmission circuits, the measurement accuracy is high, and the service life and reliability are greatly improved

4. Strong anti-interference ability

Adopting a dual balanced signal differential transmission and reception circuit

5. Powerful memory function

Automatically remember the accumulated flow rate for the first 512 days, the time and flow rate of the first 64 power outages, and the working status of the flowmeter for the first 32 days.

6. Long transmission distance and fast networking

RS485 supports wireless networking and is paired with GPRS module for wireless transmission

7. Support heat measurement

Equipped with a temperature sensor, it can achieve measurement and measurement

Product installation precautions

1. The instrument can be installed at any position on the running pipeline, and vertical installation is preferred. When installed horizontally or obliquely, the axis of the two electrodes must be in a horizontal position.
2. Require measurement management to be completely filled with liquid, and non full tubes are not allowed.
3. If the direction of liquid flow is consistent with the direction of the arrow on the nameplate, the polarity of the output signal is shown in the wiring diagram. The opposite flow direction will cause opposite polarity.
4. There should be no ferromagnetic material in close proximity to the instrument, and the installation position of the instrument should be based on strong electromagnetic fields as much as possible.

There should be no turbulence components within a distance of 5DN (inner diameter of the sensor) from the instrument. The baffle and valve should be installed at least 3DN away from the downstream side of the sensor.
