KROHNE

KROHNE is a global measurement instrumentation company founded in 1921 and headquartered in Duisburg, Germany, with its US operations based in Pembroke, Massachusetts. The company specializes in process measurement technology for industrial and municipal water and wastewater applications, offering one of the broadest electromagnetic flowmeter portfolios in the industry. Their OPTIFLUX series spans from basic models (OPTIFLUX 1050/1100) through standard water models (OPTIFLUX 2050/2100) to advanced process units (OPTIFLUX 2300/4300/5300), covering applications from clean water measurement to abrasive slurries and custody transfer. The WATERFLUX series provides dedicated water metering, with the WATERFLUX 3070 designed specifically for district metering and custody transfer of potable water. The TIDALFLUX 2300 addresses a niche but critical measurement challenge—flow in partially filled pipes (from 10% fill level)—using patented capacitive level sensing, available in sizes DN200–DN1600. KROHNE also manufactures the ENVIROMAG electromagnetic flowmeter purpose-built for the water and wastewater sector, the OPTIPROBE insertion flowmeter for large-pipe applications, and the OPTICHECK verification tool. All products use a modular sensor/converter architecture, allowing compact or remote-mount configurations with protocols including HART, Modbus, and PROFINET.
