The volumetric flowmeter installation characteristics and requirements, in order to ensure accurate measurement of the flow meter and reliability of use, it must first ensure that the chamber filled with liquid (dosing chamber) metering the flow, which is one of the principle of measurement accuracy.
In the principle of the above requirements, please be sure to follow the installation requirements and procedures.
1. Installation requirements
1.1 Flow meter should be installed before the filter, both the arrow on the housing and the direction of the media flow direction.
1.2 When the measured liquid containing gas, the gas meter should be installed before the gas separator.
1.3 Regardless of whether the piping is installed vertically or horizontally, the rotor shaft in the flowmeter is mounted in a horizontal position (ie the dial should be perpendicular to the ground), see above.
1.4 flowmeter when properly installed, if the reading is not easy, the table may be a steering direction counter dial or 90 ° to 180 °.
1.5 New flowmeter Before installation, first use the bamboo stick to push the rotor several times from the outlet (to prevent the sediment from sticking to the rotor after the factory inspection).
1.6 throttle the flow meter should be installed in the entrance, opening and closing valve installed at the outlet, start slowly when using the on-off valve, do not suddenly open the valve.
1.7 Do not purge the flowmeter with steam or gas to prevent damage to the rotor.
1.8 In the continuous use of the Department, the flowmeter to be added bypass pipe.
1.9 Before installing the flowmeter, the pipeline should be flushed. When flushing, the straight pipe section (instead of the length of the flowmeter) is used to prevent the welding slag, debris, etc. from entering the flowmeter.
1.10 Prohibit the use of water to check the cast iron, steel composition of the flow meter to prevent cast iron, cast steel rusty material.
1.11 flow meter in the use of flow size must not exceed the technical requirements. Flowmeter work in the maximum flow of 40 to 80% for the best.
1.12 For easy coagulation, crystallization medium cope heating medium pipe, a flow meter, the filter should bring insulation jacket. When used, the heating medium which is connected to the thermal insulation jacket should be fully heated and kept at a certain temperature to ensure the normal operation of the flowmeter.
