The Market for Positive Displacement Flowmeters
High Accuracy a Major Factor
Sales of Positive Displacement flowmeters
Positive displacement sales are being helped by new applications in oil & gas, cryogenics, ultra pure water processing, and other applications. Suppliers who support the aerospace industry are reporting an uptick in government spending for the military as well as for civilian and government aircraft flight applications.
Some relatively new developments focus on improved methods to increase the precision with which components are manufactured. For example, improved coordinate measuring machines make it possible to create more perfectly round pistons and other components. And as is the case with turbine flowmeters, improved bearing technology is making ball bearings more reliable and less prone to fail.

Base a Major Factor
One major growth factor for positive displacement flowmeters is the large installed base of positive displacement flowmeters worldwide. Because they were introduced more than 100 years before new-technology meters, positive displacement flowmeters have had much more time to penetrate the markets in Europe, North America, and Asia.
Installed base is a relevant growth factor because often when ordering flowmeters, especially for replacement purposes, users often replace like with like. The investment in a flowmeter technology is more than just the cost of the meter itself. It also includes the time and money invested in training people how to install and use the meter. In addition, some companies stock spare parts or even spare meters for replacement purposes. As a result, when companies consider switching from one flowmeter technology to another, there is more than just the purchase price to consider. The large installed base of positive displacement flowmeters worldwide will continue to be a source of orders for new and replacement meters in the future.
Approvals Favor PD Meters
displacement meters are specified by approval bodies for use in custody
transfer for utility measurement in residential, commercial, and
industrial applications. These
organizations include the American Water Works Association (AWWA) and the
International Standards Organization (ISO) in
their advantages, PD flowmeters face competition from new-technology
meters. In the area of oil
flow measurement, PD meters face a stiff challenge from Coriolis meters.
Because oil is a high-value product, end-users are more willing to
pay the higher prices of Coriolis meters to measure its flow.
PD meters are widely used to measure the flow of hydrocarbon
products, especially downstream of refineries at custody transfer points
and for fiscal and utility measurements.
There are two main types of PD meters used for gas utility billing— diaphragm meters and rotary meters. Rotary meters are replacing diaphragm meters in many cases. Rotary meters are smaller and lighter than diaphragm meters. This replacement is occurring for other gas applications as well. Elster (www.elster.com) is the dominant supplier in this market.

gear meters are quite popular for oil applications, especially for
downstream oil distribution involving custody transfer. Here they compete
with Coriolis meters, which are gaining market share in downstream oil
