·INTRODUCTION
 The Blancett positive displacement flow meter provides high measurement accuracy for fluids over a wide viscosity range. Applications include lubricants, fuels, chemicals and solvents, oils and greases. With only 2 moving parts, the positive displacement meter offers trouble free operation and long service life. The meter is bi-directional and it has an extremely large turndown ratio, up to 400:1 in some models - with full accuracy at extremely low flow rates.

·OPERATING
PRINCIPLES
Fluid entering the meter drives two gears. A non-intrusive sensor detects the movement of the gears and produces a square wave pulse for each gear tooth that passes the path of the sensor face. The resulting pulse frequency is proportional to the actual flow rate, and it provides a highly accurate representation of the fluid flow. The meter is relatively insensitive to changes in viscosity and there is no need for straight run piping.
