How to install magnetic flowmeters in less than optimum conditions

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.

How far does playback go on a Honeywell paperless recorder?

The two most common questions I get about paperless recorders are:

  • How far back in time can I scroll back or playback the chart?
  • How many days/weeks/months of data does the recorder save?

What people don’t realize is that the answers to these questions vary according to how the recorder’s memory is allocated.

To help you understand how the recorder’s memory works, let me explain how data is viewed and saved on a paperless recorder.

Making a Siemens clamp-on flowmeter setup record easy to read

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…”

How to pick a setpoint profile program on a Honeywell UDC3500 controller

Honeywell UDC3500 universal digital controllerYou’ve heard this phrase before: “It’s simple. But nobody said it would be easy.”

And this is exactly one of those cases.

The Honeywell UDC3500 digital controller can support up to four setpoint programs, the ramp/soak profiles used in batch control operations. But after configuring all four profiles, I was stuck on how to select the one I wanted the controller to use.

There’s no “Program Select” button on the keypad. So I was mystified on how I was going to select my setpoint profile program #3.
