A servo tank gauge transmitter is a device used in tank gauging systems to measure and transmit data about the level, temperature, and pressure of liquid in storage tanks. The STG transmitter is typically mounted on the tank and connected to a probe that extends into the tank to make the measurements.
The STG transmitter works based on the principle of servo balancing, where a servo motor is used to position a measuring device (such as a float or a displacer) in the liquid. The position of the measuring device is directly related to the level of the liquid in the tank. The transmitter then converts this position into an electrical signal that can be transmitted to a control system for monitoring and control purposes.
Servo tank gauge transmitters are used in various industries such as oil and gas, chemical, and water treatment, where accurate and reliable measurement of tank levels is critical for inventory management, safety, and compliance with regulations.
