What is the maintenance of turbine flow meter?
Turbine flowmeters are maintained through frequent inspection, routine checks, and rapid repairs to ensure accurate measurement and extend the device’s life. The following are important components of turbine flowmeter maintenance.
By following these maintenance actions, the turbine flowmeter will continue to produce precise and reliable data, ensuring efficiency and lifespan.
Rotor Inspection
Check the rotor on a regular basis to ensure that it turns freely and without friction or excessive precession. If necessary, lubricate the bushings with mild oil. Avoid using compressed air at high rates since it can harm the bushings.
Visual Inspection
Visually inspect the meter and rotor, especially for damage to the rotor blades, such as twisting or bending, which can cause miscalibration.
Cleaning and Flushing
If the liquid is clean, the meter can run for an extended amount of time without being removed. However, if suspended solids, particles, or impurities such as lint or threads are present, a filter and system cleaning are required prior to installation to avoid harm.
Seals and Gaskets:
Check that they are intact, properly seated, and free of wear. Damaged seals can cause measurement inaccuracies and leaks.
Retention Locks:
Ensure that retention locks are securely placed. These locks contribute to the proper arrangement of internal components, preventing misalignment.
Calibration Check:
To avoid measurement errors remove the rotor for maintenance or repair and restore it in the same position it was calibrated in. A factory recalibration may be required if parts are replaced or inconsistencies are discovered.
Electrical Checks:
Inspect the electrical connections for loose or incorrect contacts that could disrupt signal transmission. Measure the detecting coil’s resistance on a regular basis to ensure that the millivolt signal falls within the specified range.
Operational Testing:
After servicing, confirm that the meter is correctly reinstalled and verify fluid flow, leak detection, and proper operation.
