Kobold VKG - Viscosity Compensated Flowmeter & Switch

The KOBOLD VKG viscosity compensated flowmeter and switch offers revolutionary performance for monitoring high and low viscosity liquids with its patented compensation system that maintains accurate measurement (±5% full scale) despite significant viscosity fluctuations up to 540 cSt without requiring recalibration. Featuring a spring-loaded float design housed in a vibrant anodized aluminum body with borosilicate glass window, this versatile instrument provides reliable flow measurement for oils, water, and compatible liquids across a comprehensive range from 0.03 GPM to 21 GPM with minimal pressure drop. Available in multiple configurations—including standard flowmeter, flowmeter with one or two switching contacts, or with an additional side-mounted pointer indicator for dark fluids—the VKG adapts to diverse monitoring requirements while maintaining its universal mounting capability in any orientation. The robust construction with nickel-plated brass or stainless steel wetted components handles temperatures up to 212°F and pressures to 175 PSI, while density compensation up to 30 lbs/ft³ ensures measurement stability across fluid property variations. Equipped with cCSAus approved reed contact switches with various configuration options (N/O or SPDT) and IP65 environmental protection, this innovative instrument eliminates the traditional compromise between accuracy and fluid property changes, making it an exceptionally versatile solution for nearly any industrial liquid flow monitoring application.
