Technical & selection guides
Compare level and flow measurement technologies, explore interactive diagrams, and find the information you need to select an instrument.
Choosing a level instrument by fluid, vessel and maintenance needs
First distinguish continuous indication, point-level control and remote signal needs. Use the selection table below to compare technologies by fluid, vessel and maintenance conditions, then follow the product links.
Read the guide →Magnetic level gauges: matching materials, accessories and applications
This guide explains the float, magnetic coupling and external indication, then discusses materials and signal accessories. For an inquiry, use the 562/563/564 product page to check models, specifications and source documents.
Read the guide →Reflex vs transparent level gauges: selecting 541 or 542 for the service
For level indication, compare the bright/dark boundary of a reflex gauge. To observe liquid color or an interface, evaluate a transparent gauge. Follow the 541/542 links below and verify the medium, pressure, temperature and glass protection configuration.
Read the guide →Choosing flow meters for water, oils, chemicals, gases and steam
Narrow the technology by conductivity, viscosity, cleanliness and measurement task before choosing size. Compare electromagnetic, variable-area, positive-displacement, turbine, paddlewheel and differential-pressure methods.
