XDB306B+LCD Pressure Transmitter with LCD Display: Key Points for Installation

Pressure transmitters are essential devices for monitoring and controlling the pressure of fluids in various industries. The XDB306B+LCD pressure transmitter with LCD display is a high-quality device designed for accurate pressure measurements. This article discusses the key points to consider when installing this pressure transmitter.

Prohibit inline welding of flowmeter flanges

Avoid welding flanges directly onto the flowmeter, as this could damage the device and affect its performance.

Clean the pipeline before installation

Before installing the pressure transmitter, ensure that the pipeline is free of impurities and debris. This is particularly crucial for vertical installations where debris may accumulate at bends in the pipeline. A clean pipeline prevents foreign objects from entering the system and causing damage.

Check the rotor's flexibility

Ensure that the rotor can rotate freely before installing the pressure transmitter in the pipeline.

Proper alignment and sealing

When installing the pressure transmitter, make sure the seals are not pushed into the pipeline. The flowmeter's inlet and outlet axes should be aligned with the pipeline axes, without any noticeable deviation.

Install an expansion compensator in horizontal installations

For horizontal installations, it is recommended to install a steel expansion compensator after the flowmeter to compensate for pipeline stress and facilitate installation and disassembly of the flowmeter. The compensator should meet the pipeline's rated diameter and pressure requirements.

Test the rotor after installation

After installation, remove the bolts from the gear end face and insert a hex wrench into the internal hex bolt of the synchronizing gear. Rotate the wrench clockwise to check if the rotor rotates freely. If there is any binding, disassemble the device, remove the dirt, reinstall the rotor, and tighten the bolts.

Preserve warning labels

Ensure that the red and yellow warning labels on the flowmeter are not removed, as they provide essential safety information.

Use a protective cover for outdoor installations

If the pressure transmitter is installed outdoors, it is recommended to use a protective cover to prevent rainwater and sunlight from damaging the device and affecting its lifespan.

Avoid strong magnetic fields and mechanical vibrations

Keep the flowmeter away from strong magnetic fields and mechanical vibrations, as these can interfere with the device's performance.

Ground volume correction devices

Flowmeters with volume correction devices must be reliably grounded. However, they should not share a ground wire with strong electrical systems.

Avoid corrosive gases

The installation site should be free of corrosive gases, particularly those that can corrode aluminum alloys.

Follow the manual for power supply and wiring

If supplementary power supply or wiring is required, follow the relevant instructions in the device's manual. Failure to do so may damage the device or create safety hazards.

In conclusion, proper installation is crucial for the XDB306B+LCD pressure transmitter with LCD display to function optimally. By following these key points, users can ensure accurate pressure measurements and a long service life for their device.
