Flap type flowmeter for slurries – high viscous liquids

The Kirchner Flap Type Flow Meters are used for large flow rates in different types of process media: water, air, liquids, gases, non-conductive fluids (mineral oils, alkalis, acids), high viscous liquids (slurries) and fluids or liquids with a high content of solidifying particles.The primary measuring element of the flow meters is a flap, which is deflected by the flow of the medium. The deflection angle is a direct indication of the flow.

Advantages

• easy to install, low maintenance
• largely independent of viscosity
• wide choice of material
• explosion proof design
• opt. limit switch or analog 4-20mA output

The devices are used in water and waste water treatment plants, power stations, chemical and oleo-chemical factories, monitoring cooling and heating (furnace) systems, gravel extraction, etc.

 KLA Type Flap Flowmeter

In the standard KLA version a magnet directly transfers the flap movement to an externally mounted pointer that indicates the flow quantity on a powder coated aluminium disk.

In the KLA-GS version the quantity is directly indicated by the flap. The flap-type flow meter is equipped with hard glass screens at the front and the back which provides a direct visual display.

• suitable for slurry liquids, water, oil, suspensions, robust construction
• inidication by magnet or directly by glass
• flow direction: horizontal
• low pressure loss
• NR lining for alkalis and acids
• pipe size: DN 15 – 200
• flow up to 300 m³/h

KFS Type Flap Flowmeter

The 50 mm thick ring features a half-round plate that is fastened to a rotating spring-loaded spindle.
The angle between flap and ring changes according to the rate of flow, and a breakaway-proof magnetic coupling transfers the movement to an external pointer

• suitable for big pipes with water, acids, alkaline solutions and gases
• spring loaded flap connected to a 50mm ring
• flow direction: horizontal, top-bottom
• pipe size: DN 25 – 600
• flow up to 1650 m³/h (air 5000m³/h)
