A servo tank gauging instrument is a device used for accurate and reliable measurement of liquid levels in storage tanks. It uses a servo-operated probe that is inserted into the tank to measure the liquid level. Here’s how it typically works:
- Servo Motor: The instrument is equipped with a servo motor that controls the movement of the probe. The servo motor receives signals from the instrument’s control unit and adjusts the position of the probe accordingly.
- Probe: The probe is a rod or cable that is inserted into the tank and extends to the bottom. It is equipped with sensors, such as radar or ultrasonic sensors, that measure the distance from the probe to the liquid surface.
- Measurement: The servo motor adjusts the position of the probe until it reaches the liquid surface. The control unit then calculates the liquid level based on the position of the probe and the known dimensions of the tank.
- Accuracy: Servo tank gauging instruments are known for their high accuracy and reliability. They can measure liquid levels with precision, even in tanks with irregular shapes or internal structures.
- Applications: These instruments are commonly used in industries such as oil and gas, chemical processing, and water treatment, where accurate measurement of liquid levels is essential for process control and inventory management.
The servo tank gauging instruments are a critical tool for ensuring accurate and reliable measurement of liquid levels in storage tanks, helping to optimize processes and ensure safety and compliance with regulations.
