2002年6月5日 · The Flow Indicator - FI -would be the gauge on the meter, which is mounted locally to read the flow. If the flow is to be read remotely, as in a control console, a flow transmitter - FT - would be needed to transmit the data. So you will often see the grouping - FE, FT, FI - …

2018年6月22日 · The indicator's scale/range has to match the flowmeter's scale range. If those scale/ranges do not match then you get an incorrect reading. The 4-20mA has to represent some flow range. The flowmeter's range has to match the receiver's range. And the flow rate has to be within the 'range' to be a viable value.

2009年6月26日 · If the multivariable transmitter is a gas flow transmitter with pressure and temperature consider tagging as a flow transmitter and add Mass or a note reference outside the bubble. Perhaps the LCD can display all variables. I would reserve the Q for totalization (quantity). Try to limit the alpha prefix to three characters.

2006年7月10日 · This means the flow is partially bypassing and hot liquid finds its way through these gaps to the outlet. I do not think that is something to worry about as the reason for the recent trips. The upstream equipment are a condensate column and a reboiler. The actual FIT upstream of the coulumn shown the flow is erratic and not steady.

2005年4月21日 · Hi there . I was wondering if you can help me with the connection of signal 4-20 MA output from a KROHNE IFC 020 flow transmitter to an analog input card of PLC because i beleieve that the wiring diagramm in KROHNE manual is wrong. The analog input should be treated as 4-wire. Thank you very...

2002年10月25日 · I would stick an orifice flanged union (OFU) in the flow stream with a pretty small orifice plate (maybe a 2.5 plate for a 0.2 beta). Then a differential pressure gauge (or transducer) which reads from -10 to +10 inches would tell you the direction of flow.

2012年4月10日 · Flow is on the X axis. Head and horsepower are on they Y. If you mark the head (based on measured differential pressure) and the horsepower (based on measured motor amps) and draw vertical lines, they should be very close to each other and you can determine an approximate flow. Let's assume the pump is a little less efficient than when it was new.

2017年2月1日 · Hii, May someone help me with a way to change a promass 80 mass flow meter K-Factor. I can reach the K-Factor value from the sensor data, but unable to change it. Any suggestions to do it from the transmitter it self. I know that there is a service level access code... can someone share it wit...

2002年5月16日 · The difficult bit is staging the chillers on/off. First you must establish if there is demand for chilled water on the secondary side or not. This can be done by putting a flow metre on the by pass line between the sec/prim circuit. The flow direction and water quantity will indicate if there is too much water or too little water in the primary ...

2017年10月31日 · However, unlike your replies, API RP 551 and PIP which are international standards, as well as most of the transmitter manufacturers such like Emerson/Yokogawa/ABB/E+H etc, have been recommending the preferred tap position as 45 degrees below horizontal plane or the side for liquid measurement.(of course, these …
