The KDV series are high quality glass tube variable-area flowmeters (rotameters). This classic design is still the most widely used flowmeter style in the world today. The simple variable-area design makes the flowmeter a perfect choice when ease of installation and operation is a must. The KDV features a tempered glass measuring tube which is inert to most chemicals. This tube is suitable for measurement of both liquids and gases. Liquid flow ranges are available from 0.01 to 0.1 GPH through 265 to 2645 GPH water. Gas flow ranges are available from 0.025 to 0.25 SCFH through 670 to 6700 SCFH air. Custom Calibrations are Standard Each KDV series is built specifically for the application. The KDV will arrive with a direct reading scale which is calibrated for your operating conditions. The KDV can be calibrated for viscous media, chemicals, and various compressed gases. The scale will be provided in any measuring units the user specifies when ordering. The application datasheet provided with the operating conditions will provide all the data required to properly factory calibrate the flowmeter. A KDV for Every Application The KDV is ideal for industrial and sanitary applications. The standard model is available with NPT threaded or flanged connections. Polished finishes and Tri-Clamp fittings for food and pharmaceutical applications are available. Meters for other specialized applications can always be considered.
