682 Meter063 resizedThe 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.


  • Flow Range: 0.2 to 50 GPM (0.76 to 189 LPM); 250:1 Turndown Ratio
  • Linear Accuracy: Capable of +/- 0.1% over flow range

Slide 1
TCS 682 is Renown for Reliability and Durability

TCS 682 is the meter of choice in a wide array of applications.


The new facility features both internal and external storage tanks with room for expansion.


Premier Ag’s new liquid fertilizer and crop chemical building is part of a larger 10 acre location in Shelbyville, IN.

ICS ControlPro

ICS ControlPro software manages the facility with an intuitive user-friendly interface. The same software imports and exports tickets to/from the home office for accurate accounting and billing.

Loadout Bays

With the facility’s top and bottom loading bays, vehicles and containers of various sizes can be filled quickly and precisely.

Overhead Loadout

The overhead loadout bay includes an expanding gangway and multi-point swivel arm for safe filling.


Small batches are accurately metered/weighed with the same ICS ControlPro software as the larger bulk deliveries.


Highly accurate TCS meters precisely measure both micronutrients and crop chemicals.
