1. Briefly explain how to determine the selection of integrated and split electromagnetic flow meters. The type of electromagnetic flow meter selected should be determined based on the physical and chemical properties of the conductive liquid medium being tested. Important factors to consider: electromagnetic flowmeter diameter, flow range (maximum flow rate, minimum flow rate), lining material, electrode material, and output signal. So under what circumstances should we choose between a one-piece and a split type? Integrated type: Under good on-site conditions, it is normal to choose an integrated type, which consists of sensors and converters. Split type: The flowmeter consists of two parts: the sensor and the converter. Generally, split type is selected when the following situations occur. 1. The ambient temperature or the radiation temperature on the surface of the flowmeter converter is greater than 60 ℃. 2. In situations where pipeline vibration is significant. 3. In situations where the aluminum casing of the sensor is severely corroded. 4. In places with high humidity or corrosive gases on site. 5. Flow meters are installed in high-altitude or underground environments where debugging is inconvenient.

3. Verification Regulations for Gas Differential Pressure Flowmeters

The verification of gas differential pressure flow meters must strictly follow the JJG 640-2016 regulations, and the core process includes equipment configuration, flow point selection, and fluid pretreatment.. 1. Scope of application for verification: This applies to integrated or split type Shenmufan differential pressure flow meters, including initial verification, subsequ

ent verification, and inspection during use, including standard throttling components and differential pressure devices. two Equipment and configuration requirements: Differential pressure transmitter: At least 2 devices with different ranges should be equipped to meet the coverage requirements of multiple working conditions. three The verification of key flow point settings should include 5 feature points: maximum flow value (Qmax), 0.75Qmax, and 3 equally spaced flow points. four Control the number of detections: Each flow point needs to undergo at least 3 independent detections to ensure data stability and repeatability. five Before starting the calibration of fluid pretreatment standards, the fluid must be circulated for at least 10 minutes to eliminate pipeline bubbles and ensure the stability of the flow state. six Verification process steps

(1) After the equipment is installed for durability, perform initial state inspection and calibration;

(2) Adjust the flow rate gradually according to the preset flow point, record the differential pressure value and instantaneous flow rate; (3) Repeat the detection until it meets the convergence criteria for single point data. seven The data recording and judgment ultimately require calculating the indication error and repeatability index of the flowmeter to determine whether it meets the threshold range allowed by the regulations.
