AW Lake is a corporate from United States of America that sell some product such as Positive Displacement Meters, Turbine Flow Meters, Tricor Coriolis Flow Meter, Lake Variable Area Flow Meter, Lake Paddle Wheel Flow Meter “Flow Stat”, Monitor&Controllers, Thermal Mass Flow Meter,Flow Sensor & Pickups, Turbidity Sensor and Wireless/Bluetooth. One of the product that comes from the categories of Turbine Flow Meters is JVHS High Pressure Positive Displacement Meters.
Positive Displacement (PD) flow meters are volumetric flow measurement instruments ideal for low flow rates, highly viscous fluids, and measurement of flows involving starts and stops or pulsing. Positive displacement flow meters are similar in design to the gear pump. The principle of operation is reversed however; instead of the gears driving the fluid, the fluid drives the gears. A non-intrusive hall-effect sensor detects the movement of the gear and as each gear tooth passes the sensor, a square wave pulse is produced and a discrete volume of liquid is measured. The resulting pulse train is proportional to the actual flow rate and provides a highly accurate representation of the fluid flow. Positive displacement flow meters come in a variety of styles, and AW Lake carry three of them:
- Spur Gear
