Đồng hồ đo lưu lượng kiểu cánh quay Finetek EPR
Mô tả kỹ thuật
Nguyên lý hoạt động của đồng hồ đo lưu lượng kiểu cánh quay Finetek EPR:
The Paddle Wheel Flow Meter measures the flow velocity by using the fluidic to drive the blade rotation, and
calculates the flow rate based on the flow velocity. ERP1 series flow meter consists of flow transmitter and
pipe fitting. The light and compact design allows the user to carry, install and operate it conveniently. The
product is calibrated by professional flow test device, with the accuracy of K value reaching±3%. The
measuring range is 0.3 ~10m/s, with high linearity. Display and non-display type are both available. The
display type is built-in with accumulated flow storage device.

Ứng dụng của đồng hồ đo lưu lượng kiểu cánh quay Finetek EPR:
The Paddle Wheel Flow Meter is applicable to neutral or corrosive liquids that are non-granular or nonviscous. It connects with an analog output and pulse output signal to form a monitoring system, which can
display instantaneous flow and accumulated flow. Moreover, it can form a control circuit to adjust the valve or
operate the switch
Water treatment industry
