Scale asphalt flowmeter installation and instructions

Abstract: the scale asphalt flowmeter installation and use information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Instrument installation in normal temperature situation as far as possible, because when measuring high viscosity liquid, generally are in order to reduce the viscosity of liquid heating, then the flow in the pipe. After the instrument downtime, instrument inside filled with liquid by cooling and become sticky, such as to enable the again, must use steam or. More flow meter manufacturers choose model price quote you are welcome to inquire, here is a scale asphalt flowmeter installation and use the article details. Instrument installation in normal temperature situation as far as possible, because when measuring high viscosity liquid, generally are in order to reduce the viscosity of liquid heating, then the flow in the pipe. After the instrument downtime, instrument inside filled with liquid by cooling and become sticky, such as to enable the again, must be used on the outside of the table body heat, steam or other methods to reduce the viscosity of the liquid, the liquid viscosity reduced in the instrument to use. Or mucus will bite transmission parts, instrument damage. Do not install in place of harmful gases and strong heat radiation, prevent the meter counter parts from damage, the direction of the instrument installation shall be made on the meter housing is shown in direction of arrow and liquid flow in the same direction, the installation position should be paid attention to easy reading. Meters before the installation, pipeline must be thoroughly cleaned and in the whole pipeline system, without strict filtering devices, filters should be installed in front of the instrument, to prevent impurities into the table of the pipeline flow should not increase or decrease sharply, should avoid pipeline hydraulic shock and vibration, pressure phenomenon such as volatility, otherwise it will affect the normal work of the instrument, instrument of the pitch axis installed into a horizontal position as much as possible, immediately dial should be installed in vertical position ( Dividing & other; 0' Should be in the above) To reduce the friction between the gear and shell asphalt, reduce the wear parts. Due to the installation position is different, in order to facilitate reading, can be counters ( Header) Rotate it 90 & deg; Or 180 & deg; , each instrument factory, all with 7 # machine oil at room temperature calibration, at room temperature, the viscosity of the oil is about 10 mpa. s。 If user use this large difference with the liquid viscosity, can exchange double gear, do not sweep line by steam and water meter. Measured liquid temperature should not be higher than the specified value, otherwise, the instrument can not work normally, even to be stuck. The liquid temperature change can cause additional error viscosity influence. In addition, temperature increase caused by crescent space increases, the volume is instrument & other; Walk slowly & throughout; , measuring room for cast iron, the elliptical gear for cast aluminum, additional error is + 0. 14% / 100 ℃, the instrument shall be installed at the outlet of the pump, the flow control valve should be installed on the downstream side of the instrument. When used to open the upstream shutoff valve and then slowly open the downstream flow control valve or valve. It is forbidden to suddenly open or closed instrument 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 is measured, the measurement, the liquid mixed with gas, within the instrument must be installed upstream gas separator. Big traffic flow in excess of the prescribed zui, asphalt and wear increased with the rotating speed, and pressure loss has increased dramatically, should avoid to use. Below zui small flow rate, although still can measure, but the error increase. Meter starting flow about 2% of the zui large flow, work flow zui - good for zui big flow rate is 70% 80%, due to the measurement of high viscosity fluid, usually in order to reduce the viscosity of liquid heating, then the flow in the pipe. After the instrument downtime, instrument inside filled with liquid by cooling and become sticky, such as to enable the again, must be used on the outside of the table body heat, steam or other methods to reduce the viscosity of the liquid, the liquid viscosity reduced in the instrument to use. Or mucus will bite transmission parts, instrument damage. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
