SeaMetrics IP820B Fixed Depth Insertion Paddlewheel, Brass, 4"-8"

Impeller insertion meters designed for use with a wide variety of liquids in pipe sizes 1/2" to 3". Bodies are machined from a solid rod for maximum precision. Highquality jewel bearings and nickel-bound tungsten carbide shafts are used for extreme low friction and long life. Low-flow performance is good, although other Seametrics flow meters are recommended where extremely low flows are being measured.

The rotation of the rotor is detected by a non-drag Hall-effect sensor. Output is a current-sinking pulse, which can be sent long distances (up to 2,000 feet) without a transmitter. This signal can be connected directly to PLC's, counters, and computer cards, as well as a variety of Seametrics controls and displays.

Seametrics IP meters are ideal for chemical proportioning applications. If no display is required, a simple divider such as the PD10 provides adjustable pump pacing. For rate and total display, a modular system of electronics can be installed directly on the flow sensor or mounted remotely.

Features:

• High-quality ruby bearings for excellent low-flow performance and long life
• One easily-replaced moving part
• Pickup exerts no magnetic drag on the rotor
• Square-wave frequency output can connect directly to PLC's or counter controls
• Indicator or transmitter can be mounted on the flowmeter or remote
• Fittings are accessible in a wide variety of materials and sizes
