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
Water, oils, corrosive chemicals, steam service and wastewater call for different level technologies. Compare magnetic, glass, ultrasonic, hydrostatic and switching instruments, with links to relevant products.
Read the guide →Magnetic level gauges: matching materials, accessories and applications
A magnetic gauge combines clear local indication with separately specified alarm and transmission options. Match the 562 / 563 / 564 chamber, float and accessories to water, oils, chemicals and outdoor service.
Read the guide →Reflex vs transparent level gauges: selecting 541 or 542 for the service
Do you need a clear level boundary or a view of color and interfaces? Compare reflex, transparent and magnetic gauges by reading method, steam/chemical service, glass protection and maintenance.
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.
