Abstract: introduction to fire water meter scale and application fields of information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. According to the technical specification for fire water and fire hydrant system GB50974 - 11 2014 standards. 0. 4 the provisions of this article, high water tank outlet pipe should be set on the flow switch or directly start the fire pump, pressure switch signal GB50974 - with the new standards 2, as usual because of the weak. More flow meter manufacturers choose model price quote you are welcome to inquire, here is a discussion on fire water meter scale article details and application field. According to the technical specification for fire water and fire hydrant system GB50974 - 11 2014 standards. 0. 4 the provisions of this article, high water tank outlet pipe should be set on the flow switch or directly start the fire pump, pressure switch signal GB50974 - with the new standards 2, as usual because of the weak current signal loss and influence the rev pump reliability of the system, so the necessity of hydrant box button to start the fire pump is low, and fire hydrant button kai pump investment is larger, so the fire hydrant button should not be as direct signal and pump, only can be used as an alarm signal. Second, the GB50974 - 11 2014 standards. 0. 4 also stipulates the signal is directly start the fire pump flow switch and pressure switch, the reason is that high reliability. The flow indicator poor reliability; Misoperation is high; High water tank water level signal hysteresis; The signal only can be used as a warning signal. Stipulation that flow switch and direct pressure switch for fire pump and pump signal, flow switch is set to a certain flow value range, when the high water tank water level drop to a certain pressure, the pressure switch auxiliary startup, it can realize direct kai pump double insurance. Also can realize interlock. In order to achieve reduce misoperation, flow switch and pressure switch ( When fire water tank water level or voltage stabilizing pump does not support the fire fighting water, high water tank outlet pipe pressure drop value, pressure switch action) At the same time action as a direct and reliable measures of pump. Flow switch and pressure switch are usually set on the cistern of outlet pipe, flow switch, first action after the pressure switch, realizes the direct kai pump double insurance, thus should be set & other; Cistern flow control and fire pump device & throughout; 。 Fire water flowmeter is a kind of measuring volume flow of conducting medium induction meter, according to the principle of Faraday electromagnetic induction, with the sounding pipe axis and the magnetic field lines in the vertical tube wall installed on a pair of detecting electrodes, when conducting liquid along the measuring tube axis movement, conductive liquid cutting lines of magnetic force induced electric potential, the induction electric potential by two detection electrodes detection, numerical size proportional to the flow. Fire water meter in addition to the measured average volume flow of conducting liquid, can also be used for measurement of strong acid, strong alkali, strong corrosive liquid and slurry, pulp and paper pulp evenly liquid-solid two phase suspension liquid volume flow. Special fire water meter vertical installed on the wall of a pair of detecting electrodes, when conducting liquid along the measuring tube axis movement, conductive liquid cutting lines of magnetic force induced electric potential, the induction electric potential by two detection electrodes detection, numerical size proportional to the flow. Except the measurable general volume flow of conducting liquid, can also be used for measurement of strong acid, strong alkali, strong corrosive liquid and slurry, pulp and paper pulp evenly liquid-solid two phase suspension liquid volume flow. Fire water pipe flow meter application fields: 1. Water supply and drainage, 2. Water conservancy and water 3. Petroleum, chemical industry 4. Energy-saving monitoring, water-saving management 5. Heat measure, heat balance 6. Metallurgy, mining 7. 8 paper, ship manufacturing industry. Heating, power generation. Food and drug 10. Inspection flow, good flow tracing and gathering above is all there is in this article, you are welcome to inquire me factory flowmeter selection, quotation, etc.
fork density meter manufacturer mass flow meter is generally used to v shape coriolis mass flow meter.
