Kobold VKM - Viscosity-Compensated Flow Meter

The revolutionary KOBOLD VKM Viscosity-Compensated Flow Meter employs patented technology that delivers consistent ±4% full scale accuracy across dramatic viscosity variations up to 540 cSt and density fluctuations up to 30 lb/ft³, eliminating the measurement errors typically associated with changing fluid properties. Available in durable brass or stainless steel construction with pressure ratings up to 3600 PSIG and 5000 PSIG respectively, this versatile instrument features a spring-loaded float with precision orifice design that enables universal mounting in any orientation without requiring recalibration. The comprehensive VKM series offers flow ranges from 0.03 to 20 GPM with direct-reading scales optimized for oil applications, multiple connection sizes from ¼" to 1" NPT, and flexibility to incorporate 4-20mA output transmitters or digital displays with programmable switching capabilities. With operating temperatures up to 212°F, CSA-approved reed contacts, and the option for PNP 300mA switched outputs, this robust flow solution delivers exceptional reliability for hydraulic systems, lubrication circuits, cooling applications, and other demanding industrial processes where viscosity variations would typically compromise measurement accuracy. The VKM's innovative combination of metal construction, high-pressure capability, and patented compensation technology makes it an indispensable instrument for monitoring critical fluid systems where precise flow measurement is essential regardless of changing operating conditions.
