As energy costs and environmental concerns continue to rise, we count on our facility managers to take control of building/factory energy consumption. To reduce their companies’ carbon footprints, facility managers have begun implementing energy management programs to control their systems, optimize efficiency, and manage expenses.
But how are they doing it?
Let’s say you are trying to cool your facility. There are two steps to determining how much energy is consumed in the process. Read the rest of this entry »
Not all processes have optimal piping configurations. Learn how to identify alternative solutions for processes inhibited by piping constraints.
Siemens is hosting a free webinar on Wednesday, October 21 at 2pm EST.
In this 1-hour webinar, Siemens specialists will show you how the flowmeter can be installed and how this versatile instrument can be used to meet your application needs. They will be discussing the installation guidelines for process piping that can enhance your flowmeters’ performance.
Everyone agrees that it’s good practice to keep a record of configurations and setups for any field instrument. I’m constantly recommending it to our customers for their transmitters, controllers, recorders, and other complex configurable devices.
Siemens clamp-on ultrasonic flowmeters even have a system in place to make this process easy. By connecting the meter to a PC through the RS-232 serial port, you can use a terminal program and the SITE command to fetch a data file that holds all the instrument’s configuration data.
The terminal program can also be used — with a set of instructions specific to the flowmeter — for viewing real-time operational data, performing device setup, uploading logger data, or uploading configurations known as SITE setups.
Recently, I was called to visit a plant and look at a misbehaving flowmeter. From previous discussions with the operator, I knew he’d saved SITE setup files for every flowmeter installed in the plant.
I asked if the customer would e-mail me the setup file before my visit, so I could check out how the flowmeter was set up. My request was met with a chuckle and “Well, if you really think it’s worth it…”
When it comes to flowmeters, there are some pretty hot opinions in the control and instrumentation world about the inaccuracies of an analog totalizer, and why using a pulse-driven counter/totalizer is the way to go.
After reading some really vicious web debates on the topic, I had the opportunity to test for myself, and I was surprised at how close the resulting totals were, and how insignificant the error was.
