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 .

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.
CMC Carboxy Methyl Cellulose used as Wet-end additive,smoothing agent,surface-sizing agent in defiberination optimization.wet end.surface-sizing.
Hansstar CMC add in all parts of Papermaking process.
Strengthen water retention, improve the paint rheology,provide the carrier for whitening agent and
brightening agent in coated preparation process;Take chemical effect and enhance cohesion between the fibers,improve paper strength under wet-end process;Enhance the lubrication property between fibers,protect the fiber from over cutting,boost fiber swell up, easy beating,reduce energy consumption and save the cost in defibrination optimization process;In surface-sizing process, CMC is with excellent film form and entire film transferability and it also can form a good closure and oil-resistance on paper and paperboard surface. Furthermore, CMC is a dispersant which makes the entire sizing material or coating material enter into the stable and uniform system,reach good sizing effect.
