INTRODUCTION
Maintenance of Turbine Flowmeter
1. Daily maintenance. Patrol the turbine flowmeter and observe whether the reading display and battery power display are clear, true, and accurate. Check the sealing points of the turbine flowmeter for leakage, and deal with any leakage in a timely manner. Keep the appearance of the turbine flowmeter and its accessories clean. Check whether the instrument verification identification is clear and effective and whether the lead seal is good.
2. Monthly maintenance. Check whether the turbine flowmeter body and accessories are complete, rusted, or damaged, whether the nameplate is clear, whether the connectors are in good contact, and whether the terminal wiring is firm. Check whether the explosion-proof flexible pipe is connected reliably, and fasten it in time if it is loose; Check whether the lightning protection grounding is reliable and ensure that all connections of the lightning protection grounding wire are free of looseness and rust.
3. Quarterly maintenance. During spring and autumn inspection, disassemble, inspect and clean the matched filter dust remover. During spring and autumn inspections, the impeller and bearing of the turbine flowmeter shall be cleaned, lubricated, and maintained, and can be restored to normal use only after passing the inspection. During spring and autumn inspections, replace the LCD battery according to the battery power prompt. The spring and autumn inspection shall be carried out to check whether the explosion-proof flexible pipe is aged or cracked, and the explosion-proof performance shall be replaced in time.
Although the Supmea threaded turbine flowmeter has high quality and technology, any instrument will be damaged to a certain extent after a long time of use and work, which will affect its service life. Therefore, regular professional inspection and maintenance must be carried out for the long-term stable operation of the Supmea threaded turbine flowmeter. Only through strict control and care can we ensure that the Supmea threaded turbine flowmeter can serve customers more efficiently.
APPLICATION
A turbine flow meter measures the velocity of liquids, gases and vapors in pipes, such as hydrocarbons in fuel flow measurement, chemical flow metering, water flow metering, cryogenic liquid flow metering, air or gas flow metering, and general industrial flow metering.
Turbine flow meters are designed to maximize throughout and minimize pressure drop, maintain high flow rates over an extended flow range and offer pulse output that is linear to the flow rate.
