Precautions for Installation, Use and Maintenance of good price and quality water ultrasonic flowmeter for dn50-700mm suppliers china

1.Before using a good price and quality water ultrasonic flowmeter for dn50-700mm suppliers china, the small balls below zero should be set to red with a calibration magnetic steel, and the other balls should be set to white;

2. When users use heat tracing pipelines themselves, non magnetic materials such as copper pipes must be selected. The heat tracing temperature is determined based on the medium condition;

3. The installation position of good price and quality water ultrasonic flowmeter for dn50-700mm suppliers china should avoid or be far away from the inlet and outlet of the material medium to avoid rapid changes in local areas of the material fluid and affect the accuracy of liquid level measurement;

4. The medium should not contain solid impurities or magnetic substances to avoid jamming the float;

5. Suitable for good price and quality water ultrasonic flowmeter for dn50-700mm suppliers china, no magnetic conductive substances are allowed to approach the body. Iron wire fixation is prohibited, otherwise it will affect the normal operation of the magnetic flap level gauge.

6. Open the bottom flange and install a magnetic float (note: the heavy end with a magnetic end should be facing upwards and cannot be inverted);

7. When debugging, the upper lead pipe valve should be opened first, and then the lower valve should be slowly opened to allow the medium to smoothly enter the main pipe. Observe whether the magnetic red and white ball flipping is normal, then close the lower lead pipe valve, open the drain valve, and let the liquid level in the main pipe drop. Operate according to this method three times, and if it is normal, it can be put into operation;

8. The main pipe should be cleaned irregularly to remove impurities based on the condition of the medium;

9. For water ultrasonic flow meters that exceed a certain length (ordinary type>3 meters, anti-corrosion type>2 meters) and are suitable for DN50-700mm, it is necessary to add a middle reinforcement flange or ear bracket as a fixed support to increase strength and overcome its own weight;

10. The installation of good price and quality water ultrasonic flowmeter for dn50-700mm suppliers china must be vertical, and a ball valve should be installed between the magnetic flap level gauge and the container lead pipe for easy maintenance and cleaning;

When equipped with remote transmission supporting instruments, the following should be achieved: a) The remote transmission supporting instruments should be tightly attached to the main pipe of the liquid level gauge and fixed with stainless steel clamps (iron is prohibited); b) The sensing surface on the remote transmission supporting instrument should face and closely adhere to the main pipe; c) The zero position of the remote transmission supporting instrument should be on the same horizontal line as the zero position indication of the liquid level gauge; d) The wiring between remote transmission supporting instruments and display instruments or industrial control computers should preferably be laid separately through protective tubes or with shielded two core cables; e) After the wiring hole of the junction box is laid, it is required to be well sealed to prevent rainwater, moisture, and other intrusion that may cause the remote transmission supporting instrument to malfunction. The junction box should be covered in a timely manner after maintenance or debugging is completed.
