Positive Displacement

High accuracy and general versatility: ULTRA OVAL

The OVAL flowmeter, a positive displacement meter, consists of a pair of noncircular gears (oval rotors). It offers a wide range selection of sizes and specifications to meet the exact operating requirements of individual customers (i.e., flow rate, liquid kind, pressure and other factors). A complete line of integral registers, pulse generators, receiving instruments, and accessories are available for various types of application such as custody transfers, process controls, and energy or resource savings. The flowmeters have been used in almost every part of the industry over the years.

Precision mechanical engineering has been successfully combined with advanced electronics in the ULTRA OVAL to achieve the most desirable characteristics of the PD flowmeter. Its intelligent electronic register has substantially become compact in size and weight; an external magnet selects display modes to make it more user friendly than ever before. Parameter review, setup, and self- diagnostics are accessible through communications with the Smart type. You can choose from a broad selection for your sophisticated metering job.
