Installation Notes: 
 1 meter to prevent damage in transit, M7 indicator pointer in the rubber band with fixed wiring indicator left open the cover before it gently away and not to the pointer position changes. 
 2 Open the right cover M7 indicator, cable through the cable entries, press the rotation angle transmitter wiring diagram wiring, tighten the compression nut, the cable, then tighten the screws around the cover, the indicator is waterproof, dustproof. 
 3 Remove the measuring tube in the direction of ring opening cyclization float, float out to prevent vibration during transportation of the resistive moving parts, and as is installed. 
 4 meter should be installed vertically or horizontally without vibration of the pipeline in order to best facilitate the installation of the bypass pipe maintenance. Vertical Mount flow meter must be measured from the bottom up media. Valve must be installed downstream of the measurement location. Import and Export Department should ensure that a certain flow meter straight pipe, when the measured medium containing solid particles should install the appropriate filter, when the measured medium containing magnetic particles, magnetic filter should be installed. 
 5 Install the XFR Series Ex-type flow meter, the People's Republic of explosion hazard must be based on electrical safety procedures implemented. 
 How to use: 
 1 meter to start using the new installation, because there is no pressure on the pipeline, if the valve is suddenly opened, the instrument will float impact damage, the valve must be opened slowly. Meanwhile, in order to prevent the float vibration measurement of gas components in the measurement instrument should be equipped with a damping device. Float in case of vibration, you must install the throttle parts. 
 (2) of small diameter (25 or less) of the instrument, the instrument should be considered installed upstream of the filter to prevent dirt or other float was stolen blocked. 
 3 for gas flow, the valve should be installed in the instrument of export, to adjust the size of the flow; instability, such as gas pressure regulator device should be installed. 
 4 for gas, they should ensure that the pipeline pressure of not less than five times the flow of the pressure loss, so that the float stability. 
 Maintenance 
 1 must be clean to ensure one hundred hungry even read, especially in the orifice meter, cone surface and float tubes must be kept clean, which instrument to use for some time off after cleaning. 
 (2) two indicators cover must be sealed to prevent dust from entering, affecting the normal work. 
 3 If the instrument operation instability, in addition to the main flow of the pointer itself, beating pulse, but also consider the possibility of two-phase medium with (ie, liquid and gas exist), as long as take measures to eliminate the presence of two-phase flow, instrument can ensure stable operation.
