DSQC639 3HAC025097-00116 Temperature Sensor

DSQC639 3HAC025097-00116 temperature sensor is installed on the single-well incoming liquid pipe for real-time monitoring of the incoming liquid temperature; level sensor is installed on the separator for measuring the metering liquid level and determining the metering stage; pressure sensor is installed on the separator for measuring the pressure inside the separator. Motorised three-way valves are installed on the incoming liquid pipeline, which are controlled according to the output of the SunyPLC250 to produce the corresponding action, thus controlling whether the well is in the metering or production state.

The DSQC639 3HAC025097-00116 Programmable Logic Controller is the core of the automatic control system of the entire metering station. It is programmed to perform automatic metering at regular intervals throughout the day, switching the three-way valves of each individual well to the metering position in turn, and then switching them to the production position when metering is complete. The metered wells are converted to daily production based on the time it takes to move from the lower metering limit to the upper metering limit as it feeds into the separator.

The DSQC639 3HAC025097-00116 sends the collected temperature, level, and pressure signals, and the metering results to the host computer via the SNET network using the ModbusRTU protocol. The host computer displays and records the measured values in real time through the SunyTech software, and issues sound and light alarms to alert the duty personnel when the signals are not normal, and prints production reports regularly as needed. According to the system design, the automatic control system of the metering station has I/O points of AI: 13, DI: 13, DO: 26.
