Installation and use in the selection of diesel fuel flow meter scale

Abstract: the selection of diesel flow meter scale installation and use of information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Diesel flow meter instrument installation shall be made in the direction of the arrow as shown on instrument housing direction consistent with the direction of liquid flow, the installation position should note easy reading. Diesel fuel flow meter installed in the normal temperature situation as far as possible, do not install in the harmful gas and intense heat. More flow meter manufacturers choose model price quote you are welcome to inquire, here is a diesel flow meter scale selection to install and use the article details. Diesel flow meter instrument installation shall be made in the direction of the arrow as shown on instrument housing direction consistent with the direction of liquid flow, the installation position should note easy reading. Diesel fuel flow meter installed in the normal temperature situation as far as possible, do not install in place of harmful gases and strong heat radiation, prevent instrument meter counter part. Diesel fuel flow meter instrument of elliptical gear shaft installed into a horizontal position as much as possible, immediately dial should be installed in vertical position ( Dividing '0' should be above) , in order to reduce the elliptical gear and the friction between the shell and reduce the wear parts. Due to the installation position is different, in order to in reading, can be counters ( Header) Rotate 90 ° or l80 °. Diesel fuel flow meter gauge before installation, pipeline must be thoroughly cleaned and in the whole pipeline system, without strict filtering device, filters should be installed in front of the instrument, to prevent impurities into the table. Diesel fuel flow meter should be installed at the outlet of the pump, flow control valve should be installed on the downstream side of the instrument. When used to open the upstream section check valve, and then slowly open the downstream flow control valve or valve. It is forbidden to suddenly open or closed. Diesel fuel flow meter instrument when use, should make the inflow table filled with liquid. Within the measured liquid should not be mixed with gas, or a mixture of gas and liquid volume measurement is measured, within the liquid mixed with gas separator must be installed in front of the instrument. Of the pipeline flow should not increase or decrease sharply, should avoid to pipeline vibration, hydraulic shock and stress the phenomenon such as volatility, otherwise will affect the normal work of the instrument. Big traffic flow in excess of the prescribed zui, elliptical gear with the increase of speed increase and wear and tear, and the pressure loss increases sharply, should avoid to use. Below zui small flow rate, although still can measure, but the error increase. Meter starting flow to about 2%, zui flow quantity of work flow zui good for zui big flow of 70% ~ 80%. Used to measure high viscosity liquid, generally are in order to reduce the viscosity of liquid heating, then the flow in the pipe. When the instrument table discontinuation, instrument inside filled with liquid cooling and become sticky, such as to enable the again, must use the steam on the outside of the table body washing liquid heating methods such as heat, after waiting for liquid viscosity reduced in the instrument to use. Or mucus will bite transmission parts, instrument damage. Measured liquid temperature should not be higher than the specified value, more than the instrument will even be stuck. Liquid temperature changes will be made into the influence of viscosity additional error. 14% / l00 ℃. Each instrument factory, in 7 # machine oil at room temperature calibration, room temperature oil viscosity is about l0 centipoise. If user use this large difference with the liquid viscosity, can exchange double gear. It is strictly prohibited by the instrument with sweep line steam and water. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
