Why the tapping connections are taking above for gas service and below for liquid service?
ADCO,
2 6807We have a Yokogawa Micro-XL DCS, which is having around 300 I/O, but whenever there is any wire gets grounded in field, the 24v supply to all loops gets dipped & all the indications at DCS goes to IOP(shows input open), at present we have fixed 500mA fuses in all the lines but which does not working. Does it required to replace with lower amps fuse, then how much or is there any other solution for this.

3250I have a MRE200 amplifier for controlling a mitsubishi servo motor, I would like to know how many pulses are required to rotate the servo motor by 1 degree and what must be the pulse width
1 5089I want to know if flowrate increases in 16' pipe line what will happen to upstream pressure and why?
1 3662In 16' pipeline one pcv is installed which is controlled by PT installed at inlet of PCV.If Flowrate in pipeline increases what will happen to pressure at the inlet of pcv.
5 11401how many pulses are required by a ac induction servo motor of 4 poles with 50 Hz frequency to rotate by 1 degree?
2166what is the relation between flow and pressure.for example relationship between level and pressure is p = phg like that i want ans for this question.and also how to calculate orifice sizing and flow transmitter. pls some one ans for this questions.
3 9114What should be the ideal tapping location for pressure differential transmitter for liquid service. If the tapping taken from the top of the pipe then PDIT will work properly or not. If PDIT do not work properly then what minimum corrective action should be taken in order to solve wrong tapping locations.
