XL3 Mini Process Viscometer

Compact inline viscosity measurement for small bore pipes and tanks

The Hydramotion XL3 is a mini in line viscometer that delivers real time viscosity and temperature directly in the process. With an integrated smart head, 4 to 20 mA and RS485 Modbus outputs, the XL3 connects straight to existing DCS or PLC systems without a separate processor. Its compact, lightweight design drops into small bore pipes or tanks, giving a stable viscosity signal with no moving parts, no on site calibration and minimal installation effort.
