Mass flow of a dry solid material
A client wants to measure the mass flow of a dry solid material. Can you help? Here are the details. Carrier air flow rate = 315 tons per hour Material = granular muriate of potash (salty, highly corrosive) Output = 4-20 milliamps ...
Pulse or analog for custody transfer?
Since most Coriolis transmitters provide both pulse and analog 4-20 mA outputs for the reading, which works better for liquid custody transfer where the reading goes to a flow computer and why? How about the digital HART output from the transmitter? ...
Critical spares for plant instruments
I have to choose the critical spares for our plant instruments. I need to consider instrument reliability, manufacturer reputation, lead time, pricing, etc. I don't have any data on instrument failure in this plant. I'd appreciate if someone here can tell me how to design a good critical spares stra ...
Vortex flow meters in low flow profile
I never knew the impact vortex flow meters could have until I saw my signal trends disappear in low flow mode. So what applications suit vortex meters best? ...
Air flow meter for air handler filter?
Hi, I'm designing an air handler for filter testing. I need high accuracy flow measurement across the full 24" x 24" cross section. What do you suggest? ...
Wireless device on established system?
We need a new level and temperature system for a pump controlled by the process variable, and we want to go wireless. Can we set up a wireless device in the field and incorporate it into our current business planning and control system (BPCS)? ...
Monitoring dusty gas in ducting pipe
We have a case for monitoring dusty gas flow in a ducting pipe with a diameter of 4 meters and gas temperature up to 600 degrees Celsius. What kind of product should we choose? ...
Difference between DIN and JIS
Hi, all. I'd like to know the difference between DIN and JIS for a PT100 resistance thermometer. When using it with a digital temperature controller (Honeywell 1000 series), the controller asks for the type of RTD. How do I find out? ...

Is there any way to check my vortex flow meter online? ...
Lower and upper range values of differential pressure transmitter
On my differential pressure transmitter, I have a range from 0 to 500 psi. We use an orifice plate for creating differential pressure. Maximum DP in our gas flow is about 200 psi but it's not fixed. Can you tell me how to determine the lower and upper range values? ...
