GENERAL DESCRIPTION:
This microprocessor based paddle wheel meter is available with continuous digital display of flow rate, resettable 8 digit total flow and a non resettable grand total. The display can also be remotely mounted. For areas that do not require a display; this paddle wheel flow meter is offered with a pulse output only that can be tied into a PLC or other remote receivers. The LCD display is battery powered and provides long service up to 5 to 7 years. Unlike most paddle wheel meters this meter can handle some dirt or debris, and quite easy to clean.
Applications include: Lake or River Water, Potable Water, De-Ionized Water, Cooling Water, Sea Water, Coolants, Detergents; Corrosive Fluids, and other light viscosity fluids.
Customers include: Industries with cooling water towers; process lines; chemical additives and mixing; plating companies for spent fluids, cleaning – wash systems, irrigation, sprinkle systems, fish hatcheries and many others.
The paddle wheel, spinning at a rate linearly proportional to the velocity of the flow, activates a switch once per revolution. The time it takes the paddle to rotate, divided into the diameter of the pipe, results in the flow rate. Flow rate variations from turbulence are minimized by a microprocessor averaging process. The user can choose to display the flow rate, the accumulated flow or alternate between the rat an totalized flow. To retain the totalizer value, the rest button can be deactivated.
