Wireless Pressure Transmitters For Oil And Gas Wells Pressure Measurement

Product image presentation

A wireless pressure transmitter is a device used to measure and transmit pressure data. It transmits pressure signals to the receiving end through wireless communication technology to achieve remote monitoring and data transmission. Compared with traditional wired pressure transmitters, wireless pressure transmitters do not require wiring, are more flexible to install, and are suitable for use in applications where wiring is not easy or mobile devices are used.

Composition of wireless pressure transmitter
1. **Pressure sensor**: Detects the pressure of the measured medium and converts it into an electrical signal.
2. **Signal processing circuit**: Conditions and amplifies the electrical signal for transmission.
3. **Wireless communication module**: Transmits the processed signal wirelessly, such as LoRa, Zigbee, NB-IoT, Wi-Fi or Bluetooth.
4. **Power system**: Usually powered by batteries, and some use solar energy or other self-powered methods.
5. **Casing and protection**: In order to adapt to harsh industrial environments, corrosion-resistant, waterproof and explosion-proof casings are usually used.

Application scenarios
- **Industrial automation**: Suitable for pressure monitoring of factory pipelines, storage tanks, boilers, etc.
- **Oil and gas industry**: used for pressure measurement in oil fields and gas wells.
- **Water treatment and environmental protection**: monitor water treatment equipment and pipeline pressure.
- **HVAC system**: detect pressure changes in air conditioning and HVAC systems.
- **Smart agriculture**: monitor water pressure in irrigation systems.

Advantages
- **Flexible installation**: no wiring required, saving installation time and cost.
- **Easy maintenance**: reduce repairs due to wiring damage or wear.
- **Remote monitoring**: supports long-distance signal transmission and is suitable for distributed monitoring.
- **Strong adaptability**: can be used in harsh environments, such as high temperature, high humidity or flammable and explosive occasions.

Wireless pressure transmitters improve the intelligence level of equipment by combining sensing technology and wireless communication technology, especially in the Industrial Internet of Things (IIoT).

The correct position of the transmitter process pipe depends on the medium being measured. In order to select a reasonable installation location, the following points should be considered:
1) Corrosive or overheated media cannot be in direct contact with the transmitter;

2) Prevent slag from depositing inside the pressure tube;

3) Use the pressure tube as short as possible;

4) The hydraulic height in the two pressure pipes should be balanced;

5) The pressure pipe should be installed in a place with small temperature gradient and fluctuation;

When measuring gas pressure, it is required to install a pressure-inducing pipe connected to the process pipeline within 45° of vertical upward or vertical upward direction. The transmitter should be installed above the side pressure port to allow liquid to be discharged into the process pipeline. When measuring liquid pressure, it is required to install a pressure-inducing pipe connected to the process pipeline in the horizontal direction or within 45° downward in the horizontal direction. The transmitter is installed under the pressure port on the side to allow gas to be discharged into the process pipeline.

Specification

The installation process of wireless pressure transmitter is relatively simple and flexible, but in order to ensure its measurement accuracy and communication stability, some installation points need to be paid attention to. The following are the installation steps and precautions for wireless pressure transmitter:

Installation steps

1. **Select the installation location**
- Make sure that the installation location can reflect the actual measured pressure and avoid dead corners or pipe bends.
- Choose a place without interference and avoid strong electromagnetic interference sources, such as frequency converters, radio transmitters, etc.
- Ensure that the signal can be transmitted smoothly to the receiving end. For long-distance transmission, make sure there are not too many obstacles.

2. **Connect the measured medium**
- Use a suitable connector to connect the transmitter to the pressure pipe or pressure interface.
- Make sure that the interface is well sealed to avoid leakage affecting the measurement accuracy.
- Avoid direct exposure to strong vibration or drastic temperature changes during installation.

3. **Power supply and wireless communication configuration**
- Check the battery power or external power supply to ensure that the transmitter has sufficient power supply.
- Configure the wireless communication module and set communication parameters, such as frequency, ID address, data transmission rate, etc. Ensure that the communication configuration matches the receiving end.
- For occasions with explosion-proof requirements, ensure that explosion-proof batteries or power supplies that meet the standards are used.

4. **Signal test**
- After the installation is completed, perform a signal test to confirm that the data can be transmitted to the receiving end normally.
- Test the measurement accuracy of the pressure transmitter and calibrate the transmitter to meet the measurement requirements.

5. **Fix the transmitter**
- Use appropriate fixing brackets or flanges to firmly install the transmitter to avoid looseness.
- If it needs to be installed outdoors, it is best to use a protective cover to protect the device from natural factors such as wind and rain.

Precautions

- **Avoid vibration**: If installed in a place with large vibration, vibration reduction measures should be taken, such as adding vibration reduction pads.
- **Regular maintenance**: Check the battery power of the device and replace or charge the battery regularly.
- **Protective measures**: For harsh environments, ensure that the transmitter has a sufficiently high protection level housing, such as IP65 or higher waterproof and dustproof level.
- **Lightning protection and grounding**: When installing in areas with frequent lightning, consider lightning protection measures and do a good job of grounding.
Installation suggestions for special occasions

- **High or low temperature environment**: Select a transmitter suitable for the temperature range to avoid damage to the equipment due to high or low temperature.
- **Explosive environment**: Use explosion-proof wireless pressure transmitters and ensure compliance with explosion-proof standards and requirements.
- **Marine or corrosive environment**: Select a transmitter made of corrosion-resistant materials to extend the service life of the equipment.

Correct installation can ensure the measurement accuracy and data transmission stability of the wireless pressure transmitter and extend its service life.

Product maintenance
