These heavy-duty in-line flowmeters / totalizers display flow rate and accumulated flow in GPM or LPM. This compact yet robust design makes them ideal for use in manufacturing, pilot-plant, or quality control areas. All flowmeters measure linearly across a range and record a cumulative volume plus a resettable volume. Meters are factory-calibrated using water but can store two application-specific K-factors determined in-process. To conserve power, the six-digit display automatically turns on with flow and then turns off four minutes after flow ceases. The internal parts are simple to replace for easy maintenance¿contact our Application Specialists for details. Meters operate on two lithium batteries (included). Remote installation of the flowmeter body is possible using the optional remote installation kit (order separately). Replacement battery kits, output modules, and calibration containers may be ordered separately.
