1. What maintenance is needed for electronic film flowmeter in daily life?

The daily maintenance of electronic film flowmeter mainly includes four aspects: appearance inspection, electrical connection, measurement accuracy, and membrane maintenance. Appearance and installation inspection • Installation status: Regularly check whether the flowmeter is installed firmly, whether the connection parts are loose or deformed, and ensure compliance with installation specifications. • Appearance cleaning: Use a clean and tidy soft cloth to wipe the shell to prevent dust, oil stains, and other impurities from accumulating and affecting the operation of the equipment.

2. Electrical connection inspection • Line inspection and routing integrity: Check whether the power and signal lines are damaged or aged to ensure reliable connection.

. • Grounding inspection: Ensure good grounding, prevent static interference, and ensure electrical safety

3. Maintenance of flow measurement accuracy • Zero point calibration: Regularly perform zero point calibration in the absence of flow, and adjust according to the manual if drift is found. • Comparative measurement: Compare data with standard flow meters. If there is a significant deviation, recalibration or repair is required.

4. Special maintenance of the diaphragm. • Status observation: Check whether the diaphragm is damaged, aged, or deformed, and replace it immediately if any abnormalities are found. • Regular cleaning: Clean the attached impurities on the membrane according to usage to avoid affecting measurement performance.

2. Maintenance and Calibration Methods for Rotameters

After understanding the importance of rotameters in industrial

measurement, daily maintenance and regular calibration are key to ensuring their long-term stable operation and accurate measurement.

. The relevant methods are summarized as follows. 1. Maintenance method 1.1 Appearance inspection: Regularly check whether the casing and glass tube (if any) of the flowmeter are damaged or cracked. Damaged glass tubes may cause medium leakage and need to be replaced in a timely manner. At the same time, check whether the connection is firm, whether there is looseness or leakage, and ensure good sealing. 1.2 Cleaning For flow meters measuring clean fluids, regularly wipe the glass tube with a clean and tidy soft cloth to maintain its transparency for observation. If the fluid contains impurities, internal sedimentation may affect accuracy. It is necessary to choose a suitable cleaning agent for internal cleaning according to the characteristics of the medium, and be careful to avoid damaging the components. 1.3 Rotor inspection: Observe whether there is wear, corrosion, or impurities adhering to the surface of the rotor. Wear and tear can cause inaccurate measurements, and replacement needs to be considered. Check whether the rotor runs smoothly and whether there is any jamming; Catching may be caused by foreign objects or friction with the pipe wall, and needs to be cleaned or adjusted. 1.4 Environmental maintenance: Ensure that the installation environment is dry, ventilated, and free from moisture and corrosive gases. If unavoidable, a protective cover can be added. At the same time, avoid severe vibrations and impacts to avoid affecting the internal structure and accuracy. 2.
