(OG2) Special 700 Bar – Oval Gear Flow Meters & Sensors
OG2 700 Bar High Pressure Oval Gear Flow Meter/Sensor
These compact rugged, high-pressure oval gear flow meters/sensors are designed to give high performance with a low cost of ownership. There are two flow ranges to choose from, 1 and 4 L/min full scale. The standard inlet and outlet are 1/8” or ¼” female threads. The output is frequency pulse that is proportionate to flow. The body is 316 St St with Viton® ‘O’ ring seals internally.
At the heart of the PG2 high pressure oval gear flow meters/sensors are a pair of toothed oval gears one of which contains chemically resistant magnets. Rotation is detected through the chamber wall by a Reed switch giving approximately 1100 or 2050 pulses per litre passed. The output is a voltage free contact closure. This combination of materials and technology ensures a long life product with reliable, accurate operation throughout.

High Pressure OG Meter Output
Magnets in the gears are detected using a Reed switch sensor. These sensors are very reliable. The reed switches are capable of over 1000 million operations. Being a simple contact closure they are classed as simple apparatus. And are easily interfaced with most existing electronic circuits.
NOTE: High tensile bolts are used on these meters and therefore they should not be used outdoors or in a corrosive environment.
