Canada is the fourth-largest oil-producing country and natural gas producing country around the globe. The Canadian oil and gas extraction industry generated a revenue of $118.5 billion in 2017. The sector makes up a large portion of the global economy.

Companies that operate in the oil and gas industry require reliable measurement devices to ensure the accuracy and efficiency of their offshore operations. It enables them to maintain high operating efficiencies and safety of the drilling operation.

The weighing systems, in particular, must be able to withstand harsh external conditions and show precise readings. Therefore, companies should invest in high-quality weight indicator systems to produce accurate readings on compression, tension, and weight.

Here are three key factors that can affect your weight system’s accuracy:

Factor#1: Accuracy Of The Load Cell

The loan cell is a fundamental component of a weighing system – it plays a crucial part in ensuring the accuracy of the results. When the load is applied, the load cell bends and converts the mechanical force into an electrical signal.

A malfunctioning load cell can compromise the precision of the weighing system. Moreover, several other elements affect the accuracy of a load cell, including creep, non-linearity, response time, and more.  Temperature changes can also cause weighing errors. 

Factor#2: Misalignment Of The Load

Weighing system accuracy is also influenced by the load itself. If the load isn’t applied correctly—for instance, it’s aligned improperly—then it can halt the transmission of the total load to the load cells, leading to inaccurate results.

The misalignment can be caused by rigidly mounted piping, askew load point assembly – the bent structure under the load cell – system bending, or other reasons. A high-quality weight system will ensure that load cells support all the weight to be measured.

Factor#3 Interference

As mentioned earlier, weight systems depend on the load cells that convert mechanical force into an electric signal. Interference near the weighing machine can disrupt the electric signal, which leads to accurate results.

Noise generating devices like RFI and EMI can produce signals that can meddle with the electric signal of a load cell. Furthermore, environmental factors like condensation, moisture, and temperature can also create additional interference that affects the final weighing results.
