Hi Shot Servo 1/Servo type ultra micro flowmeter


Flow can be measured accurately by continuously controlling the flow using the servomechanism so that the differential pressure between inlet and outlet of the flow is zero. A positive displacement flowmeter best suited for measuring the injection flow of engine injector, injection flow from filling nozzle, micro flow of laboratory or test plant, and micro additives in various production processes.
