The use of glass rotameter scale and maintenance

Abstract: the use of glass rotameter scale and maintenance information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. In industrial production activities, glass rotor flow meter because of its easy to carry, low cost, widely used, etc was popular, here we introduce glass rotor flowmeter maintenance in the use of some of the key. 1. Install the glass rotor flow. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the use of glass rotameter scale and maintain article details. In industrial production activities, glass rotor flow meter because of its easy to carry, low cost, widely used, etc was popular, here we introduce glass rotor flowmeter maintenance in the use of some of the key. 1. Glass rotor flowmeter before installation to must do the pipe welding slag, clean up the clutter. 2. Glass rotor flow meter must be installed perpendicular to the ground the slope may not exceed 2 & deg; 。 Otherwise it will affect the measurement accuracy. 3. If measured medium is dirty or containing magnetic particles, filters should be installed at upstream of metal tube float flowmeter or magnetic filter. 4. In order to ensure that the glass rotor flowmeter measurement accuracy, should be increased in the inlet flow meter is not less than 10 dn of straight pipe, outlet of not less than 5 dn straight pipe, when measuring the regulating valve must be installed on the downstream side of the meter. 5. The installation of the meter should be able to properly support the pipeline vibration or reduce the axial load meter, it should increase the support of fixed flow meter. 6. If measured medium is big pulsating flow or two phase flow, the buffer should be installed at upstream flow meter to eliminate or weaken the pulsation, ensure the flow of the medium is single-phase stable, at the same time, the suggestion of the flowmeter using damping type. 7. Glass rotor flow meter is used for gas, should ensure that the pipe work pressure not less than five times the flow pressure loss, the flowmeter can stable normal action. 8. Of electric remote transmission and take alarm limit switch meter before use, open the cover, according to the connection here is correct. Unscrew the limit switch for alarm type of screw, the user according to the need to set limit alarm position, and tightening the screws, used after recovery. 9. In order to facilitate the maintenance of flowmeter, magnetic filter cleaning and user line of regular maintenance, it is recommended to use the bypass pipe. 10. If open the rotor flow timing, no pressure or due to the pipe system has not yet reached instrument using normal working pressure, must be slowly open valve, until the system is normal, instrument for use, otherwise easy to cause a pointer to beat or rotor suddenly hit and damage phenomenon. 11. According to the instrument indicator of warning signs, remove transport resistance moving parts, prevent the rotor vibration in recovery before using the instrument. 12. Users, if be density and water will not flow at the same time, or the parameters of the gas being measured and the manufacturer shall not working state and at the same time for flow meter reading value for conversion. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
