Low Cost Viscosity Compensated Flowmeter
from Kobold Instruments

KOBOLD VKA viscosity compensated flowmeters and switches combine proven and reliable construction with affordable pricing.

Available for flow rates from 2 GPH to 26 GPM, the VKA series viscosity compensated flowmeter and switch is a viable alternative to the VKG and VKM series of viscosity compensated flow metering products. Internal modifications reduce the pressure loss in the viscosity compensated flowmeter to 8 PSI, while still maintaining a compensated viscosity range of 30 to 300 cSt.

Special Features:
Flow ranges 2-6.3 GPH to 8-26 GPM OII
All Metal Bodies in Brass
Adjustable Switch Available
Pressure 3600 PSIG Maximum
