Interchangeable Meters
Flange-to-Flange Drop-In Replacement Meters


The Oval Gear meter is a precise positive displacement flowmeter incorporating a pair of oval geared rotors. These meters are capable of measuring the flow of a broad range of clean liquids. Stainless Steel flowmeters are suited to most water-based products, chemicals, and lubricating liquids. The flow meter is available as a blind pulse meter with a non-factored pulse output capable of interfacing to most monitoring and control instrumentation.
The TCS 700 rotary flow meter combines excellent accuracy with low-pressure drop. The TCS 700 rotary flow meter has a compact size and lightweight design that offers minimal maintenance and long service life. This meter is built with advanced materials of construction for a broad range of measurement applications and is accompanied by a full selection of accessories and electronic registration.

The TCS 700 series rotary flow meter has a simple and efficient meter design consisting of a housing and three rotors that rotate in unison within the measuring chamber. The absence of wear, from no metal-to-metal contact within the chamber, eliminates any deterioration in accuracy and provides a long service life.
The rotors are supported by bearings inserted into two bearing plates, where at the end of each rotor shaft is a timing gear. The timed rotation between each rotor is then transferred through the calibration adjuster to the register, giving a consistent and superior measurement of accuracy.
The TCS 682 reciprocating piston flow meter combines outstanding accuracy (0.1% of flow rate) with one of the widest turndown ratios in the industry (250:1). The TCS 682 reciprocating piston flow meter has a rugged industrial design that is tolerant of changing viscosities, temperatures, and liquids with suspensions and solids.
This proven design has over 80 years of unmatched performance and continues to provide the very best in flow measurement, backed by our industry-leading 10 YEAR WARRANTY (5 YEAR WARRANTY - LPG)!
The TCS 682 series flow meter is a true positive displacement meter that has a unique inline design consisting of three reciprocating pistons operating within their respective measuring chambers. Each piston works in a manner similar to an automobile engine. The pistons are fitted to a wobble plate, which has a shaft extending from its upper surface and a valve pivot attached beneath it.
The valve pivot drives a sliding valve from the piston to piston as a known amount of product flows through each cylindrical bore, controlling the sequence of events in a smooth mechanical motion. This smooth mechanical motion is then transferred through the driveshaft to the register.
