5.1 Site Survey and Planning

Before deployment, conduct a thorough site survey:

• Identify all monitoring points: Map every location requiring pressure or temperature measurement

• Assess power availability: Determine which points have power and which require battery operation

• Evaluate network coverage: Test cellular (NB-IoT/4G) signal strength and LoRa gateway placement

• Classify hazardous areas: Determine the required explosion-proof or intrinsic safety rating for each location

5.2 Installation Considerations

Mounting:

• Ensure the process connection matches the transmitter (1/2″ NPT, DIN, flange, etc.)

• Use appropriate sealants or gaskets for the media being measured

• Consider vibration isolation if mounting on reciprocating equipment

Antenna Placement:

• Position the antenna for optimal signal transmission

• Avoid metal obstructions between the transmitter and gateway/cellular tower

• For LoRa networks, ensure the transmitter is within range of the gateway

Battery Management:

• Note the installation date and expected battery replacement date

• Consider battery type (lithium, replaceable vs. non-replaceable)

• Monitor battery status remotely through the transmitter’s telemetry

5.3 Integration with SCADA and IoT Platforms

Wireless transmitters must integrate seamlessly with existing control and monitoring systems:

• SCADA Integration: Most wireless transmitters support standard protocols (Modbus, MQTT, etc.) for integration with SCADA systems

• Cloud Platforms: Data can be sent directly to cloud-based IoT platforms for visualization and analytics

• Alarm Management: Configure threshold alarms for pressure and temperature deviations

Integration Example: A heavy oil wellhead deployment might use ISA100 wireless pressure transmitters paired with a gateway, RTU, and Ignition SCADA front-end. This provides end-to-end visibility from the wellhead to the control room.

5.4 Data Configuration and Optimization

To maximize battery life and data utility:

• Set appropriate reporting intervals: More frequent reporting consumes more battery. For most monitoring applications, 15-60 minute intervals are sufficient.

• Configure alarm-based reporting: Program transmitters to report immediately when pressure or temperature exceeds thresholds, rather than waiting for the scheduled interval.

• Enable data logging: Ensure transmitters have onboard memory to store data if communication is temporarily lost.

5.5 Maintenance and Lifecycle Management

While wireless transmitters are low-maintenance, a proactive approach ensures reliability:

• Remote diagnostics: Use remote configuration capabilities to check device health without field visits

• Battery replacement schedule: Plan battery replacements based on expected life and actual consumption data

• Firmware updates: Keep transmitter firmware current to benefit from performance improvements and security patches
