Question: 1 / 400

What is the purpose of sloped tube manometers in the context of low pressure gas line testing?

To measure high pressure gas flow

To indicate atmospheric pressure

To measure low gas line pressure accurately

Sloped tube manometers are specifically designed to measure low pressures, which is crucial in the context of low pressure gas line testing. Their design allows for greater sensitivity and precision in detecting minor pressure changes. The inclined position of the tube means that even small variations in gas pressure produce noticeable movements of the liquid within the manometer, making it easier for technicians to read and analyze low pressure readings accurately. This accuracy is vital for ensuring the safety and efficiency of gas systems, as low pressure conditions can often indicate leaks or other issues that must be addressed. Thus, the primary function and purpose of sloped tube manometers align directly with measuring low gas line pressure accurately.
