2. What is the minimum diameter specification of the water flow meter calibration device

The minimum diameter specification of the water flow meter calibration device varies depending on the device type and manufacturer, and the common minimum diameters are DN10 and DN15.

1. The minimum aperture of typical publicly available devices 1 The standard version water flow standard device of Aisite Instrument (Shanghai) Co., Ltd. can test instrument diameters ranging from DN10 to DN800, with a minimum calibration diameter of DN10

2. The flow calibration device of Mike Sensor Co., Ltd. can meet the production coarse chain calibration of DN15-DN500 caliber flow meters; The volumetric rock jet water flow verification device is suitable for the verification of small and medium-sized equipment ranging from DN15 to DN200, with a minimum calibration diameter of DN15 for both.

3. What are the specifications of a water flow meter?

Introduction: A water flow meter is composed of two important parts: a sensor and a converter, and its operation is based on the law of electromagnetic induction.

. The water flow meter can measure the volumetric flow rate of some conductive liquids, and the conductivity resistance of these conductive liquids must be greater than 5 μ S/cm, so it is an inductive instrument. Lets learn about the specifications of water flow meters and some other related introductions together. Specifications of the water flow meter: 1. Pipelin Specification of water flow meter
