Expert’s answer: THUM installation

YES, YOU CAN! Yes, you… okay, back to your question. It is possible to install the THUM wireless adapter on a Micro Motion 5700 HART protocol. Though, the THUM cannot provide the energy for the flow meter.

The Micro Motion is a 4-wire device. This means that it has 2 cables for the power supply and 2 more cables for the signal. You will need a local power supply for the meter and THUM. With help of the wireless connection you will receive a digital signal.

There are different ways to install the THUM adapter. You need to know if the field device is either a 2- or 4-wire device and if it is passive or active. The procedure to install is described in the technical manual. Below you see a reference of the THUM installation:

Temperature measurement between two parts
In reality, I could likely settle for thermocouples one/inch or so, but that would be a lot of inches at 36×36″. Does anyone know any devices, sensor matrix, and or material that may work here?

Pressure monitoring solutions
We need pressure measurement at my plant on a 20-inch pipe, and we don’t know which pressure transmitter we should use. Any advice?

Pressure process accuracy
I need to make a calculation based on a value of recorded pressure, but I need to know the measurement error. If the manufacturer publishes an accuracy of 0.02 percent, is this only when first shipped or is it always this accurate? Is the accuracy of Bourdon tubes any different?

THUM with Rosemount 8712
We have a wirelessHART network, and now I need to add a new flow meter to the network. What do you recommend for THUM installation?

Rosemount 8712 and another flow sensor
Can you have a Rosemount 8712 installed with another brand sensor?

Rosemount 8732 communication!
I can’t get communication between my handheld and the Rosemount 8732. Can you tell me why they’re not talking to each other?

K-factor for Rosemount 8712
The measurement of my flow meter is not correct, and we’re investigating what’s happening here. Can you tell us how to check the K-factor on the transmitter?
