DESIGN
The 682 series piston flow meter is a true positive displacement flow meter that has an inline design consisting of three (3) reciprocating pistons operating within their respective measuring chambers, where 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 piston to piston as a known amount of product flows through each cylinder bore, controlling the sequence of events in a smooth mechanical motion. 

FEATURES
•  Superior Accuracy over the entire flow range
•  Low Maintenance
•  Long Service Life
•  75 years of proven performance and acceptance
•  Wide Viscosity Range - up to 50,000 SSU (11,000 CPS)
•  Meets NIST, OIML and many other international weights & measures certifications - NMI Approved for Re-Sale / ATO Claims

REGISTER OPTIONS

PLC or digital controllers for fluid process management. Stock or customized units are available from our UL 508A approved engineered systems.
MID:COM is a leading manufacturer of electronic meter registers, on board computers and accessories. The most common applications are on Propane and Petroleum delivery trucks.
Veeder-Root is the leading manufacturer of Meter Registration products throughout the world, now with the Electronic Registration EMR3.
The 7887 Meter Register totalizes and displays high speed deliveries and transactions in large, 3/4" easy-to-read figures. Displays a 5 digit resettable totalizer and 8 digit non-resettable totalizer
Meter Register and Ticket Printer combine to produce clean, detailed printed records of high-speed fluid deliveries and transactions
The Meter Register and Preset Counter provide automatic preset batch control. The control function will shut-off (2-stage) when predetermined quantity is delivered.
The Micro Switch assembly has two double chamber internal switches to provide Full Flow, Low Flow and Off Control for the 7889 preset counters.
The dry reed (1:1 or 10:1) and solid state (100:1) pulse transmitters provide fast and accurate signaling for remote indication, totalizing and data monitoring systems
This swivel adaptor allows the register to be rotated to any desired angle before delivery or while meter is operating.
Tray switch prevents a pump or valve from turning on until the register counter has been reset. Also used for resetting external digital displays after a transaction is finalized.
