Lake Monitors offers a rugged line of flow rate gauges, alarms/switches, transmitters and hydraulic system analysers. The basis for our product, the sharp-edged, variable-area, measurement method, provides accurate and repeatable flow rate measurements for both liquids and gases.

From April new manufacturing techniques at the Wisconsin facililty will see the Lake range of meters leap forward from their compeition, offering:

• Improved accuracy: All units will have 2% (fulls cale) or better accuracy over the full flow range
• State of the art calibration: Automated calibration software with high-res vision will ensure the flow profile of each meter is accounted for individually
• Uniquely scaled meters: After individual calibration data is created, each meter will be precisely marked with a laser engraving system

Benefits:

• Lake Monitors' sharp-edged orifice provides a more reliable and accurate reading in applications where fluid viscosity varies.
• The unique design of the monitor allows installation in any piping orientation.
• The high-strength magnetic coupling between internal and external components eliminates mechanical seals and linkages that can fail.
• With more than 20 different port options (including BSPP, NPT and SAE), three body materials (AL, brass, 316SS) and a choice of standard or custom flow ranges / calibrations / measuring scales, Lake Monitors has the correct product to match your system requirements.
• Large range of stock (in Sydney) with short factory lead-times (3-4 days ex. USA) on non-stocked items.
• Most Lake variable area meters are backed by a five year parts and labor warranty against all defects in materials and workmanship.

Flow Meter Operating Theory (refence picture above)

Enclosed within a high pressure casing (A), a high strength magnet (F) in tandem with the sharp-edged annular orifice disk (E) is pressed towards the zero flow rate position by a linear rate compression spring (G).

A tapered metering pin (D) is positioned concentrically within the annular orifice disk and provides a variable-area opening that increases by the square of linear displacement of the orifice disk.

Fluid flow creates a pressure differential across the orifice disk, pressing the magnet/orifice disk duo against the compression spring. Flow rate is read by aligning the magnetically coupled follower (C) with the graduated scale located within the environmentally sealed window (B).

The variable-area orifice design provides pressure differential and orifice displacements that are linearly proportional to fluid flow rate.
