Product Description
Introduction
- Sm35aws-fl telemetry indicator is designed for the indicator diagram test of pumping Wells, set load and acceleration displacement measurement, low power embedded microcontroller, low power remote wireless digital communication technology in one of the high-performance wireless sensor products, is driven by low power wireless communication network technology LoRaWAN, And the development of digital oil and gas production Internet of things one of the important front-end acquisition equipment. Through its own load sensor and acceleration sensor, it can measure the suspended point load and optical rod displacement of the pumping unit online synchronously and connect to LoRaWAN communication network to realize the direct remote transmission of the work chart data representing the working conditions of the pumping unit well. The high reliability design adapted to the industrial environment, as well as the characteristics of high precision, simple installation, convenient maintenance, environmental protection and durability have won the recognition of users, not only in domestic Shengli, Daqing, North China, Changqing, Xinjiang, Qinghai and other major oil fields have been promoted and applied, but also in overseas oil companies. This product has obtained a number of patents, with independent intellectual property rights, counterfeiting will be prosecuted.

Long light 2 to 20 seconds |
Joining the ZigBee network |
Add ZigBee network operation instructions after the sensor is powered on or reset for the first time. |

Send regular sequence
|
When LoRa (memory) is successfully added to the network, the normal sequence is sent. Every time the sequence is sent, the base station needs to wait for the reply. There is no reply after 30 seconds, and the sequence is resend. |
|
|
Sends power diagram packets |
After the power map measurement is completed and LoRa (memory) is successfully added to the network, the transmission power map data packet is divided into multiple packets. The data transmission of each packet needs to be confirmed by the base station, otherwise it will be re-transmitted. The whole process will last about 30 minutes depending on the network communication situation. |
4.2
installation
1) Configure well name and site configuration (establish local wireless data communication network with RTU); Note: For ZigBee wireless communication mode only.
2) In order to ensure the transmission efficiency of power diagram and reduce the energy consumption of sensor battery, the base station distance should be reasonably arranged to ensure the signal strength RSSI≥ -110dbm when the terminal sensor works normally.
3) The sensor is placed horizontally between the suspension pressure blocks according to the direction of "installation Direction Mark" by professional personnel to ensure that the "bearing column" is evenly loaded; After installation, be sure to tighten the "sealing insurance" reliably through the supporting screws.
4) Conduct a power diagram test immediately at the well site using the testing software provided by the company. For details, see SM Series Digital Wireless Sensor Operation Manual.
4.3 Precautions
1) If the load sensor is not used for a long time, please disconnect the battery, or set the measurement type to deep sleep mode, and then restore it when using.
2) If any problem occurs during the use of the product, please contact our technical service personnel in time; Do not remove the sensor by yourself, otherwise no warranty!
3) The battery packs used by this sensor are explosion-proof products provided by our company. If we replace other battery packs not provided by our company, our company cannot continue to guarantee the explosion-proof performance of this product and will no longer be responsible for the risks and consequences.
4) Please be familiar with SM Series digital Wireless Sensor Operation Manual before field debugging operation.
