The pipe must be completely full at all times. Air bubbles or air pockets in the flow stream will adversely affect the

reading. A small amount of back pressure is recommended in horizontal runs of pipe.

The F-1000 is powered by two AAA batteries. Life expectancy is one year minimum.

Although the F-1000 is designed to withstand outdoor conditions, a cool, dry location where the unit can be easily

serviced is recommended. The life of the LCD display will be severely reduced when installed in direct sunlight. Do

not install the meter so that the LCD is in direct sunlight.

The F-1000 can be mounted on horizontal or vertical runs of pipe (see figure 4, 5 and 6). Mounting at the twelve

o'clock position on horizontal pipe is recommended. Mounting anywhere around the diameter of vertical pipe is

acceptable, however, the pipe must be completely full of water at all times. Back pressure is essential on downward

flows.

The F-1000 accuracy is affected by disturbances such as pumps, elbows, tees, valves in the flow stream. Install the

meter in a straight run of pipe as far as possible from any disturbances. The distance required for accuracy will

depend on the type of disturbance.

Note: The F-1000 should be serviced by qualified persons only.

The F-1000 accuracy is based on steady, undisturbed flow with a fully developed turbulent flow profile. Pulsating,

swirling and other disruptions in the flow stream will effect the meter’s accuracy.

The F-1000 is factory calibrated to ± 2% of full scale rate reading. When measuring total flow, accumulated error over

time must be considered. Accuracy is based on laboratory testing of nominal pipe dimensions. Your actual accuracy

will vary based on your actual pipe I.D. And other installation factors.

There are two basic types of flow profiles; turbulent and laminar (see figure 3). Turbulent flow exists when the

speed of the fluid flowing in the pipe is nearly constant across the entire width of the pipe. This is typical of low

viscosity fluids; like water, flowing at high velocity. Laminar flow exists when the speed of the fluid flowing in the

center of the pipe is greater than the speed of the fluid at the outer edge near the pipe wall. This is typical of high

viscosity fluids flowing at low velocity. Because the F-1000 is measuring the fluid near the pipe wall only (especially

in larger pipe sizes), a constant flow velocity across the flow stream is required.

(due to swirling)

To determine which type of flow exists in your installation, the following is required:

Flow rate of the fluid in GPM -Q

Specific gravity of the fluid -G

Pipe inside diameter in inches -D

Fluid viscocity in centepoise -V

Use the following equation to determine the REYNOLDS NUMBER:

REYNOLDS NUMBER = 3160 x Q x G

D x V

Flow conditions with a Reynolds Number greater than 4000 is fully developed turbulent flow. A Reynolds Number less

than 2000 is laminar flow. The F-1000 requires a Reynolds number greater than 4000 to maintain accuracy.
