I am working on Ver 7 of SP Intools. This is the first time the program is used and was installed in late Feburary. We have entered all the instruments, spec sheets, loaded JB with Device panels and cables. Connected the 24 pr from field JB to control room Marshalling panel. The next step is...

My first introduction to steam flow measurement was in 1975, at this time all the meters I came accross had the orifice taps located on the side. The root valves were installed horizontally and the transmitter tubing sloped down to the transmitter. Installations in some older units used...

I had run into an installation a few years ago that had a number of insertion turbine meters installed on their steam system. I thought this was odd because of the moving parts of the turbine and the temperature of the steam. They didn't have any maintenance records so I am not sure how much...

I had this concern a few years ago on some transmitters I was powering from a junction box. I moved the junction box about 20ft to get it outside the Class I, Div 2 area. I realize this probably isn't a solution for you. Another time I installed the Z-purge option, of course this requires an...

First, I have enjoyed reading all the answers. I am involved in Instrumentation and Interlock systems. My experience with double block and bleed valves has been on the fuel gas line on boilers, furnaces, and incinerators. When the boiler shuts down or trips the two block valves close and the...
