Industrial instrument model shortlist for EPC engineers, plant maintenance teams and procurement specialists.
This guide maps common measurement duties to searchable model families from Rosemount, Endress+Hauser, Yokogawa, KROHNE, WIKA and SAMSON. Use it to create an RFQ shortlist; final selection must be checked against process data, hazardous-area classification and the current manufacturer datasheet.
Searching only for “a flowmeter” or “a pressure transmitter” rarely produces a reliable specification. A usable inquiry starts with the industry, measurement task, fluid, operating range, materials, process connection, output and certification. The tables below provide concrete model families for more than 50 common application duties.
How to use this industrial instrument model list
- Find the industry and measurement duty closest to your application.
- Shortlist two or three model families with the required measurement principle.
- Confirm minimum, normal and maximum pressure, temperature and flow.
- Confirm wetted materials, line size, connection, installation environment and approvals.
- Send the full process datasheet for configuration-code and accessory verification.
Important: Model-family inclusion is not a guarantee of suitability. Options within one model can differ substantially by sensor, range, liner, electrode, diaphragm, antenna, housing, protocol and approval.

Frequently asked questions
Can one model be used in every industry?
No. A model family may support many configurations, but hygienic, corrosive, cryogenic, high-pressure, oxygen, SIL and hazardous-area duties require specific options and documentation.
Why include exact model numbers?
Model numbers make technical research and replacement planning faster. They also help procurement teams compare measurement principles and prepare a better RFQ. They do not replace sizing or configuration review.
Can Santan Fluid help with replacement and cross-reference?
Yes. Send the existing nameplate, configuration code, datasheet and process conditions. We can prepare a like-for-like check or a technically appropriate alternative shortlist.
Request a model selection and quotation
