Tape Level Gauge in the Oil Industry

Tape level gauges play a significant role in the petroleum industry by accurately measuring and monitoring liquid levels. This article delves into the application of steel tape level gauges in the petroleum industry, covering their working principles, selection guidelines, installation requirements, as well as advantages and disadvantages.

Tape Level Gauge in the Oil Industry

Working Principles

The working principle of a steel tape level gauge relies on the buoyancy principle and tension sensor technology.

Float. The float is immersed in the liquid being measured, and its buoyancy changes with the variation of the liquid level.

Steel tape. The steel tape is connected above the float and extends along the direction of the liquid level change.

Pulley. The pulley is fixed at the top of the liquid level instrument and is used to guide the movement of the steel tape.

Tension sensor. The tension sensor is installed at the end of the steel tape to measure the tension on the steel tape, thereby determining the height of the liquid level.

When the liquid level rises, the float rises accordingly, and the tension sensor detects an increase in tension on the steel tape; conversely, when the liquid level drops, the float descends, and the tension sensor detects a decrease in tension on the steel tape. By measuring the change in tension on the steel tape, the height of the liquid level can be determined.

Selection Guidelines

When selecting a steel tape level gauge, the following factors need to be considered:

Nature of the liquid. Different liquids have different densities and viscosities, so it is necessary to choose a steel tape level gauge suitable for the properties of the liquid.

Operating environment. Consider the operating environment conditions of the level gauge, including temperature, pressure, corrosiveness, etc., and select models that are resistant to high temperatures, high pressures, or corrosion.

Measurement range. Select a suitable measurement range according to the variation range of the liquid level to ensure that the level gauge can meet the actual application requirements.

Accuracy requirements. Choose a suitable model based on the accuracy requirements of the application scenario; generally, higher accuracy level gauges are relatively more expensive.

Installation Requirements

Correct installation is the key to ensure the normal operation and accurate measurement of the level meter. The following are the points to be noted when installing the liquid level gauge with steel strip:

  1. Fixed and stable. When installing the level meter, make sure the level meter is fixed firmly and free from external vibration and shock.
  2. Avoid interference. Avoid installing the level meter in the area of liquid agitator or liquid flow to prevent external interference from affecting the measurement accuracy.
  3. Keep clean. Clean the float and steel band of the level meter regularly to prevent dirt from blocking or accumulating and affecting the measurement accuracy.
  4. Calibration. After the installation is completed, carry out calibration and calibration to ensure that the measurement results of the liquid level meter are accurate and reliable.
