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.
Part of my job as the technical specialist at Lesman is to make sense of new products and upgrades, and figure out what’s really going to matter most to our customers.
Sometimes it’s just a matter of a much-needed new functionality, or better configuration tools, easier mounting, or switching to the most current form of data storage.
In the case of Siemens’ latest ultrasonic controller, it’s all that and more.
Siemens (and Milltronics) ultrasonic controllers and transceivers, like the HydroRanger, MultiRanger, and OCM-III have been around for years with no significant improvements. Instead of updating these devices, Siemens has done a complete redesign, and introduces the SITRANS LUT400 as the first device in the new ultrasonic controller family.
Here are my initial thoughts on this new player in the ultrasonic game.
A customer who had had lots of experience with Milltronics and Siemens ultrasonics was installing his first SITRANS LR560 radar level transmitter. They had worked with it in the shop beforehand, going through most of the settings. They even tested it by setting it up to shoot against a file cabinet and used a tape measure the check the indicated distance value.
Everything checked out OK in the shop.
When they installed the transmitter on the top of the bin, they changed the transmitter’s sensor mode parameter from the distance mode they used in the shop for testing to level mode. After aiming, the level value shown in the local display was dead nuts on, but the 4-20mA signal going back to the control room was way off.
The bin was a third full. The 4-20mA showed it about double that. Not only that, the 4-20 was going in the wrong direction. The bin was emptying and the HMI reported an increasing level value. Someone realized that an inverse-acting output was typical of a distance value, so they reconfigured the sensor mode to distance. That got the 4-20mA much closer to a distance value, but it was still not exactly what it should be, and besides, the goal was to read level, not distance, in the control room. What was going on?
