The gas industry has long been looking for new and accurate methods for measuring large volumes of gas at high pressures. Orifice metering is the most common method, but one major drawback is its rangeability. When a station has variable flow rates, a technician may be required to change orifice plates quite often. Another drawback is the space that is required to place an orifice meter. Not all stations will have ample space for a setting. Turbine meters have grown to have a large acceptance throughout the industry, and they do have a wide rangeability. Unfortunately, they are more expensive and are not as durable as orifice meters. For stations with dirty gas, large filters may be required to protect the meter. Multipath ultrasonic meters may soon be a valuable option to satisfy some application problems. They are proving to be very accurate. They are quite durable since there are no moving parts in the flow stream. Their rangeability is proving to be greater than a turbine meter`s, and one of their greatest benefits is that they are bidirectional (capable of measuring gas flows into or out of a station).
