I'm curious as to the collective school of thought on plotting in the latest releases of Autocad. Previously, all plotting referenced the "Printable area" of a sheet. Now in 2005 (and I believe 2004), you can select "Edge of Paper" as well. Since all of our page setups were previously...
I attached an image of a map to the drawing in model space. I then go to Layout (paper space), and open a viewport to size the map. When I add my leaders and text in paperspace, it dissappears from the display beneath the image in the viewport. DrawOrder has no effect on elements in another...
why not just try BIF themselves. The original BIF was bought by a group of former employees and are still doing business in flow metering.

They should be able to help you with the calibration of the existing flow element so you can install a modern DP transmitter.
We're about to upgrade from 2002 to 2005. We currently use named page setups to control all print/plot settings. I'm trying to find out if we're going to need to modify anything about our current print/plot procedure to accommodate the new Acad version. Has anyone encountered problems moving...
This house must have a check valve in the supply line. Water expansion due to thermal effects would normally just push the water back out into the supply line in normal household services. Something has to trap the water to get a buildup. Why are you using check valves on service supplies?
Get a copy of the "George Cliffird White Handbook of Chlorination". This is the bible for disinfectant use in the water and wastewater industry in the US. It gives all the info you need for sizing of pipes.
I've had two versions operate successfully, though not the exact same versions you're talking about. We did it with 2000i and 2002. As long as both STAYED on the machine, everything was fine. Problems developed when the 2000i was removed. It made the remaining 2002 copy unstable...
Most wireless access points and routers have twin antennas on the rear. What's the reason behind this? And if you're trying to extend the range of the wireless link by using an external directional antenna, which antenna port do you use, or does it matter?
I'm in the water industry and we periodically have to design pipelines for supply to remote areas. I know that the petroleum industry deals with long pipelines routinely. I'd like to know what type of controls are generally used for booster pumping stations along the line. And also, what's...

Over 600 miles (1,000km) with one pump? What kind of discharge pressures are we talking about here. Most pipelines I'm aware of have some in-line booster stations along the pipeline to boost pressure.
No offense taken Art. However, I've seen very few instances of powered discharge valves in series with conventional check valves. If you have a check valve, why would you need to open and close a discharge valve, other than surge avoidance. If it is for surge avoidance, we're probably talking...
I'm not sure why everybody is saying to not start the pump against a closed discharge valve. It is common to start centrifugal pumps against a closed discharge valve, especially large pumps. Take a large water pumping station for instance, where multiple pumps are piped in parallel to...
Many times, we've used a DC control relay for long distance control of motor starters. At some distance, a 3-wire control (start-stop) with an AC magnetic starter will not be acceptable due to the capacitive coupling in the Stop circuit. Even though the NC stop button is pressed, the...

The tables give the flow at 100-inches water column differential pressure and the permanent loss is in the table column "Loss". The permanent loss is generally 7-15% of the differential.
You are most likely going to experience what's referred to as "frazil ice". This is ice crystals that form on water plant or power plant cooling water intake screens at freezing temperatures and below. It's a common phenomenon. You can read about the cause in the following link...
No you can't use this for voltage input. The model number is a clue. notice the "I" at the end of the model number. This designates current. A-B also has a 1746-NI16V module (notice the "V" at the end of the model number) which is for voltage inputs. If you want the...
OK Bris, I'll give you an answer. Every single water utility I know (and I've been in the business for over 30 years) has an official policy of total compliance with the OSHA regs. That means that every vault or tank entry is done by the book, with atospheric monitors, etc. I've also...
Here in the United States, OSHA establishes the requirements for "permit-required confined spaces". The federal regulation 29-CFR-1910.146 covers this. This regulation is for general industry and contains procedures to protect employees in general industry from the hazards of...
