Flow Control - Kobold

The cutting-edge KOBOLD KAL-D Compact Thermal Flow Switch delivers reliable flow monitoring for water-based liquids through advanced calorimetric technology that requires no moving parts, ensuring exceptional performance even with particulate-laden fluids. Featuring microprocessor-based temperature compensation for precise measurement across varying conditions, this stainless steel instrument detects flow velocities from 0.15 to 6.6 ft/sec while providing field-adjustable setpoints via an intuitive LED bargraph display and potentiometer adjustment. The compact insertion-type design minimizes pressure loss while withstanding operating pressures up to 580 PSIG and temperatures from -4°F to 176°F, with clean-in-place capability up to 250°F for sanitary applications. Available with multiple connection options including NPT, BSP, and M12x1 threads, and configurable with either NPN or PNP transistor outputs in normally open or normally closed configurations, this versatile instrument adapts perfectly to diverse industrial requirements. Protected to NEMA 4/IP65 standards and constructed with premium 316L stainless steel wetted parts, the KAL-D offers exceptional durability alongside sophisticated electronic protection features including short-circuit safeguards for its 400mA switching capacity.

The versatile KOBOLD KSM Plastic Flowmeter delivers reliable flow measurement for aggressive chemicals and corrosive substances with its all-plastic construction featuring no metal components in the fluid path. Available with either durable Polysulfone (for highly corrosive applications) or Trogamid® measuring tubes (for moderately aggressive media), this variable area flowmeter provides ±4% full scale accuracy while withstanding pressures up to 145 PSI and temperatures to 140°F. The device's highly visible red PVDF float and large dual-scale display show both direct flow readings (GPM/SCFM) and percentage values, making monitoring simple across a wide measurement range from 0.06 to 264 GPM for liquids or 0.5 to 400 SCFM for gases. Optional bistable reed contact switches with IP65 protection can be easily added for automated flow control and alarm functionality, with convenient field-adjustable markers ensuring precise setpoint positioning. Featuring robust PVC connections (available in glue socket or NPT threaded options) and chemical-resistant EPDM seals, this shock-resistant instrument provides reliable service in water treatment, chemical processing, laboratory, and other demanding environments where metal flowmeters would quickly deteriorate.

The KOBOLD KSV Economical Micro Flowmeter provides precise measurement for minimal liquid and gas flows with its versatile design featuring a polysulfone body and your choice of brass or stainless steel connections. Engineered for light industrial applications, this vertical-mount variable area flowmeter delivers consistent performance with ±6% full scale accuracy and exceptional ±1% repeatability in a compact, easy-to-read format. Available with flow ranges from 0.04 GPH to 20 GPH for liquids or 0.3 SCFH to 100 SCFH for gases, the KSV offers outstanding chemical resistance and can withstand sterilization temperatures up to 250°F. The optional integrated needle valve provides enhanced flow stability, particularly useful when measuring gas applications where fluctuations are common. With 1/8" NPT female connections and an 87 PSI maximum operating pressure, this economical instrument offers reliable metering performance while maintaining excellent resistance to acids and alkaline solutions.

The innovative KOBOLD REG Valve delivers precise flow regulation in fluid systems without requiring external power or manual adjustment. Engineered to maintain consistent flow rates despite pressure variations of up to 145 PSI differential, this self-actuating balance valve brings reliability to multi-user networks where stable distribution is essential. Available in both brass and stainless steel constructions with 3/4" NPT connections, the compact REG valve handles temperatures up to 572°F while withstanding pressures of 2900 PSIG. Its maintenance-free operation and passive activation mechanism eliminate the need for electrical controls or pneumatic lines, making installation straightforward and reducing long-term operational costs. The REG's robust design features specialized internal components including a 304 SS ring cone and 301 SS regulating orifice that work together to automatically adjust to pressure changes, providing steady flow for water and compatible water-like liquids in industrial applications.

The innovative KOBOLD SMN Flow Switch delivers exceptional performance with its ability to detect extremely low liquid flow rates while maintaining minimal pressure drop during high-volume operation, making it ideal for critical process monitoring applications. Unlike conventional designs, this ingenious device utilizes a magnetic float suspended in a cylindrical tube that works against a compression spring, activating an adjustable reed contact when flow reaches the predetermined threshold. Available in brass construction rated to 3600 PSIG or stainless steel rated to an impressive 5000 PSIG, the SMN provides reliable switching between 0.4-13 GPM (on) and 0.25-1 GPM (off) while operating in temperatures up to 212°F. The NEMA 4X/IP65 rated housing with DIN 43650 connection ensures dependable performance in demanding industrial environments like cooling circuits, high-pressure cleaning systems, and contaminated media control applications. Featuring vertical or horizontal mounting flexibility and CSA-approved electrical options including standard N/O or optional SPDT contacts, this compact flow monitor combines precise low-flow detection with remarkable high-flow handling capability in a single, maintenance-friendly package.
