The KOBOLD PSR/PS Series paddle-type flow switches can be used wherever a simple, economical and yet reliable monitoring instrument is required for flow switching applications. The KOBOLD TSK Series flap style flowmeter employs a hinged flap (vane) within the flow stream. As the flow rate changes, the flap rotates in its fitting. The KOBOLD DPT Series paddle-wheel flowmeter uses a unique, patented target system to measure the flow of liquids. KOBOLD’s DWU, DWN and DWS flowmeters and flow switches are based on the paddle, or static plate, principle and are ideal for use in applications where dirt and solid grain contaminants are of concern. KOBOLD DWD Series paddle-bellows flowmeters and flow switches include a flow rate transmitter with digital indication of the actual flow rate, analog output and two adjustable all-or-nothing relays indicating the switching point for monitoring limit values. KOBOLD FPS paddle-bellows flow switches are used wherever reliable control for minimum or maximum liquid flow is required.
Rotating Vane Flowmeter and Switches
Kobold Rotating Vane Flowmeter and Switches are suitable for a wide range of applications for measurement and control of low viscosity and high viscosity liquids. KOBOLD Instruments Inc. combines the quality craftsmanship and reliability of German design with the cost-effectiveness and quick turn-around of a North American manufacturing facility. This unique combination enables KOBOLD to offer customers the best instrument value in the industry.
The KOBOLD DF Series paddle-wheel flow sensor offers the variety of seven material combinations, allowing the DF to be used with compatible water-based, low-viscosity liquids and many aggressive water-based chemicals. The DF series also includes flowmeters with digital output, batch controller and totalizer. The KOBOLD DON Series oval gear positive-displacement flowmeters are the preferred choice for measuring clean, high and low viscosity liquids such as lubricating/hydraulic oils, diesel fuels, chemicals, solvents, resins and pastes. The DPM Series flow sensor uses the pelton wheel principle to measure the flow of water and water-based, low-viscosity liquids that are optically transparent. The KOBOLD DRZ Series rotary piston positive-displacement flowmeter combines economy with high performance. The KOBOLD DRG Series paddle-wheel flow sensor offers the winning combination of compact size, low cost and versatility, which makes it the perfect OEM flow sensor.
Flow Measurement without Moving Parts
KOBOLD provides a variety of solutions for flow measurement without moving parts using induction, oscillation, ultrasonic, air velocity, thermal, differential pressure, and inertia.
The KOBOLD DMH Series magnetic-inductive flowmeter is used to measure and monitor the volumetric flow rate of fluids, pulps, pastes and other sufficiently conductive materials, with no moving parts and virtually no system pressure loss. The KOBOLD DOG-4 flowmeter is used for flow measurement of gases. KOBOLD DUK Series compact ultrasonic flowmeters are used for measuring, monitoring, and batching of low viscosity (water-based) fluids. KOBOLD DVZ Series vortex flowmeters with no moving parts are the perfect solution for applications where reliability and low cost are desired. The PIT Series insertion magnetic flowmeter with no moving parts is designed to measure the flow velocity of conductive liquids in large diameter pipes. KOBOLD KEL Series differential pressure liquid flowmeters with no moving parts are designed specifically for applications in difficult environments. The Heinrichs TME Series general purpose Coriolis mass flowmeter from KOBOLD Instruments is a very accurate, rugged design built for general purpose mass flow measurements of liquids and gases in most chemical, petrochemical, oil and gas applications.
KOBOLD flow indicators provide visual indication of flow activity in an economical housing made from a variety of materials to suit a range of air and liquid flow indication applications.
