Recently, I was helping a customer troubleshoot the analog input on his Siemens MultiRanger 200.
For common troubleshooting, using voltage values to confirm a zero, mid point and span is all that’s needed. I find it easier to put a voltmeter across the analog input and read the voltage drop than to wire an amp meter into the circuit to read directly, but that assumes that the analog input’s resistor value is a known. For the most commonly used input resistance (250 ohms), the equivalent voltage drop is 1.0 to 5.0V.
Being the guy who actually reads the user manuals, I looked in the Siemens manual to find the input resistance, and it’s not there.
Custody transfer flow meters are used to determine how much of a commodity changes hands in exchange for some monetary, financial or other recognized trade consideration.
All custody transfer applications involve at least one buyer and one seller. During custody transfer, accuracy is of great importance to both the company delivering the material and the recipient.
In order to ensure reliable and accurate measurement, devices are certified for custody transfer by a nationally recognized body. For Coriolis flow sensors, custody transfer approvals are mandated by the US National Conference on Weights and Measures office.

If I’ve heard it once, I’ve heard it a dozen times when talking with a Siemens support guy while evaluating a problematic ultrasonic level measurement application,
“What’s the echo confidence and strength?” “What’s the noise measurement?”
Those are numbers that quantify the echo quality: the floor values for echo confidence and strength and the ceiling value for the noise. I’d look up the value and the guy on the phone would tell me whether the number was good, bad or so-so. Finally, someone wrote down what those values should be, and they’re worth filing for future reference.
