Motherwell Tank High Accuracy Tank Servo Gauge
2800i Tank Servo gauge is designed for use in custody transfer tank
Custody Tansfer Level Servo Gauge (2800i) with Water and Profiling option and inputs for Temperature Measurement
The 2800i Servo Tank Gauge is a high accuracy gauge designed for use in custody transfer tank gauging applications. Our Servo Gauge exceeds the requirements of UK weights and measures standards for tank gauges.
Our Servo gauge is a reliable, versatile and accurate automatic tank gauge, the servo gauge has been designed for ease of installation with minimal moving parts.
The Servo gauge is designed to measure all kinds of liquid and can be situated either in free space or stillwells. The Servo can easily be linked to our tank gauging system or to an existing tank monitoring system.
The Gauge include the options to link the gauge to feature like temperature measurement (spot and average temperature are available) temerature profiling, full integration to management system, density measurement and much more.

Principle of Operation
Motherwell’s servo tank gauge operates on the principle of displacement measurement. A small displacer on a measuring wire is unwound from a drum and accurately positioned in the liquid medium using a servo motor. The weight of the displacer is precisely balanced against a magnetic coupling and the wire drum. When the displacer is lowered and touches the liquid, the weight of the displacer is reduced because of the buoyant force of the liquid. As a result, the torque in the magnetic coupling is changed and this change is measured. The signal, an indication of the position of the displacer, is sent to the motor control circuit. As the liquid level rises and falls, the position of the displacer is automatically adjusted by the drive motor. This system provides an outstanding accuracy of our servo gauges. Servo gauges are ideally suited for light and middle distillates of petroleum.
