Before installing the metal tube float flowmeter , be sure to clean the welding slag and debris in the pipeline. In order to ensure the measurement accuracy of the metal tube floater flowmeter , a straight pipe section of not less than 10DN shall be added at the inlet end of the flowmeter, and a straight pipe section of not less than 5DN at the outlet end. The adjustment control valve must be installed downstream of the flowmeter when measuring. . If the medium to be measured is a large pulsating flow or two-phase flow, a buffer shall be installed at the upstream of the metal tube float flowmeter to eliminate or reduce the pulsation, so as to ensure that the flow of the medium is single-phase stable, and at the same time, it is recommended that the flowmeter be best used. Damping type. If the measured medium is dirty or contains magnetic particles, a filter or magnetic filter should be installed upstream of the metal tube float flowmeter .
In the modern industries, advanced ceramic component is very commonly used in many, many electron vacuum devices, like electron tubes, high voltage feedthru, high current feedthru, vacuum interrupter, vacuum capacitors/Thyristors, X-ray tubes and power switches and so on.
The key point is what a metal coating covers on the surface of ceramic body, or ceramic base to achieve the vacuum hermetical and sealing, such as nickle plating, sliver plating, gold plating, copper plating and Tin plating. The main features for vacuum ceramic component as below:
-Extremely high bond/brazing strengths
-High mechanical strength
-Minimum electric resistance and vacuum tightness
-Excellent insulation
The typical form for vacuum ceramic component is to be as an insulator, ceramic packaging and ceramic body etc.

The installation of metal tube float flow meters should be able to properly support the vibration of the pipeline or reduce the axial load of the flowmeter, otherwise the support of the fixed flowmeter should be increased. In order to facilitate the maintenance and repair of metal tube float flowmeter, cleaning of magnetic filter and regular maintenance of user's pipeline, when the metal tube float flowmeter is used for gas measurement, it should ensure that the working pressure in the pipeline is not less than 5 times of the flow The pressure loss of the meter allows the flow meter to stabilize and operate normally. Before using the remote transmission and metal tube float flowmeter with alarm limit switch, open the meter cover and wire it correctly according to the wiring diagram. For the alarm-type screw that loosens the limit switch, the user sets the limit alarm position as required, and tightens the screw to use it after recovery.
