Safety ALWAYS wear protective clothing, eye protection, and follow standard safety procedures when handling corrosive or personally harmful materials. NEVER use this flow meter with flammable or combustible liquids. NEVER use this flow meter in a hazardous environment. ALWAYS verify chemical compatibility with the flow meter and pump materials of construction before operation. ALWAYS make sure the pump and hose are properly supported.
Section 1 - Installation NOTE: Avoid exposing the LCD for prolonged periods to direct sunlight or the life of the LCD may be reduced. 1. Determine which direction the flow meter display is to face. It is bi-directional and can face either to the right or left but must be kept in the upright position. 2. Wrap Teflon tape on threads of both ends of flow meter (Item 1). Screw Hose Barb Adapter (Item 2) onto discharge end of flow meter. Tighten securely by hand or wrench, being very careful not to over-tighten.
Changing display from Rate or Total Programming Menu Flow Chart Calibration While the FM-2000 has been calibrated at the factory, field calibration is possible to increase accuracy at a given flow. Use the flowing steps for field calibration. NOTE: If the meter has been previously field calibrated, the scale factors (Rate Scale and Total Scale factor) will need to be reset to factory default values. Refer to “Step Six” using the default values from Figure 2.
For example, the specific gravity on the MSDS for 93% sulfuric acid is shown as 1.84. 8.33 pounds per gallon x 1.84 = 15.33 pounds per gallon (density) for 93% sulfuric acid. f. Divide the net fluid weight by the fluid density to determine volume. Record the known volume _____. For example, the net weight is 41.65 pounds; the fluid is water with a density of 8.33 pounds per gallon; 41.65 divided by 8.33 = 5 (gallons) g. Divide the known volume by the reading on the meter.
d) When finished, press the button. The screen changes to the RATE 2 (“2” is in left corner of display) screen. Do no make changes on this screen. Go to the next screen by pressing the button. e) The screen changes to the RATE 3 (“3” is in left corner of display) screen. Do no make changes on this screen. Go to the next screen by pressing the button. f) The screen changes to the Total 1 (“1” is in left corner of display) screen. Enter the Total Scale Factor from Step four.
Section 3 - Accuracy The accuracy of these flow meters is published as Full Scale Accuracy. This means the amount of error is relevant to the Full Scale, which is 50 gpm for the FM2000. For example, if the flow meter is displaying 5 gpm, and you measure the actual flow to be 5.4 gpm, then your full scale accuracy is calculated as (Measured-Actual) / Full Scale...or 5 minus 5.4 divided by 50 which equals .008 or .8%. On the other hand, the Acutal Accuracy is calculated as 5 minus 5.4 divided by 5.
