Single flange pressure transmitter released in measuring liquid level of the common failure analysis time: 2019 - 04 - 12 read number: zero

Single flange pressure transmitter is high performance measuring instrument, used in industrial process full range of differential pressure, pressure measurement, with analog or digital output signal. Through liquid level flange installation, transmitter can be installed directly on the tanks being measured, precision measuring various differential pressure and liquid level of tank, it can fully meet the demand of your level measurement. Both flange and plug-in flange products are flat, suitable for high viscosity medium or suspension liquid measurement. Due to the isolation diaphragm is very thin, is the weak link corrosion resistance, so the liquid membrane material with 316 l, hartz C - 276, monel, tantalum, etc. , can be applied to different situations of the anti-corrosion requirements, according to the parameters such as concentration, humidity, pressure measured medium suitable for corrosion resistance is given in appendix table reference for reasonable selection, such as strong corrosion occasion can choose anti-corrosion structure transmitter. Tin meter single flange pressure transmitter typical failure analysis: a, single flange level transmitter display on the high side and fluctuations in different time periods. ♦ ♦ installation location: atmospheric storage tanks failure phenomenon: instrument set up after the initial display is normal, liquid level changes biggish error occurs, static liquid level at the time showed fluctuations. ♦ hazards: may cause overflow or empty cans and waste or impact the production. ♦ failure cause analysis: 1, guide pressure pipe ( Capillary) May be leaked. 2, medium is too thick. 3, tanks and exhaust. ♦ analysis points: single flange level transmitter can't be blocked, emphatically analyzed the single flange level transmitter itself and the dielectric properties, in addition to consider environmental impacts. ♦ check processing result: by analyzing the basic equipment and media influence, through the level interval judgment it is sensitive to temperature fluctuations, thus may be canned the abnormal pressure media guide, capillary has space. Remove the suction flange to under observation for a period of time, have improved, so as to determine for negative pressure capillary wind gap. After the troubleshooting of the demolition of the capillary. Second, the single flange level transmitter volatility. ♦ installation location: carbon dioxide absorption tower. ♦ fault phenomenon: single flange level transmitter liquid level display frequently between zero and a relatively fixed value fluctuates up and down. ♦ harm: can't normal adjustment, prone to mixes up and overpressure explosion. ♦ failure cause analysis: lower suction flange equipment packing appear congestion fluid, the suction side of the frequent squeezes gas liquid two phase or solution space. ♦ processing: open clogged and find out why, prevent again.
