| Flow Probe Product Description（便攜式流速儀英文說明書） |
Turbo-Prop Sensor The Flow Probe incorporates the unique Turbo-Prop propeller sensor, which uses the most accurate positive displacement technique available for velocity sensing. The Turbo-Prop is designed to shed debris and is protected inside a 2 inch diameter housing. The probe housing may be placed directly on the bottom of a pipe or streambed for measuring low flows down to 2 inches in depth. The flow meter propeller rotates freely on its bearing shaft with no mechanical interconnections for minimal friction. Magnetic material in the propeller tip passes a pickup point in the water velocity meter handle producing electrical impulses that are carried to the readout display by an internal cable. The Turbo-Prop is easily removed for cleaning or replacement. NOTE: Global Water recommends recalibrating the water velocity computer every time the Turbo-Prob sensor is replaced. Contact our Technical Support department for more details. Water Velocity Computer The water velocity computer receives an electrical signal from the propeller, amplifies the signal, and converts the reading to feet per second (or meters per second, depending on programming). The large LCD screen displays average, minimum, and maximum water velocity readings. Up to 30 sets of minimum, maximum, and average data readings can be stored in the water velocity computer. These data points can be reviewed on the computer screen for later analysis. The water velocity computer has a water-resistant housing and incorporates a unique four-button operation for changing functions and resetting the display. The water velocity computer is powered by a non-replaceable battery that will last approximately five years with normal use. Low battery warnings will also display as appropriate. Flow Probe Handle The Flow Probe handle can telescope from 3.7 feet to 6 feet in length (FP111), 5.5 feet to 15 feet (FP211), or 2.5 feet to 5.5 feet (FP311). The handle is constructed of anodized aluminum for light weight and long life. The 15 foot length of the FP211, Flow Probe, allows for measuring sewer flows from street level and measuring stream flows from low bridges. While the 2.5 foot collapsed length of the FP311, Flow Probe is ideal for carrying into remote flow monitoring areas. A 3-foot (1.7-feet for the FP311) mylar coated staff gauge (graduated in hundredths of a foot and centimeters) is attached to the lower section of the water velocity probe for instant water depth measurements and accurate propeller positioning. True Velocity Averaging The Flow Probe can be used to measure the true average water velocity of a channel's flow. As long as the turbo-prop sensor is in the water flow, the computer will average the water velocity. One reading is taken per second, and a continuous average water velocity is displayed. To obtain the true average velocity the flow probe should be slowly moved throughout the cross sectional area being measured. Once the reading becomes steady, the true average water velocity of the cross sectional area is obtained. This allows for highly accurate flow measurements, which average the differences in velocities that occur throughout a flow's cross-section and with water surges over time. The average water velocity can be saved by pressing the SAVE button and reviewed later. Optional Swivel Head The Flow Probe Swivel Head option allows you to rotate the flow probe's turbo prop to + 90 degrees from it's standard position. This option lets the flow probe take water velocity measurements in hard to measure areas such as vertical pipes on water tanks or swimming pool drainage systems. Optional Alignment Fin Significant errors can occur when measuring water flow other than directly parallel to the direction of flow. The Global Water Flow Probe Alignment Fin is designed to help orient the flow probe parallel to flow when the end of the probe can't be seen well due to the depth or cloudiness of the water. To use this accessory, immerse the flow probe and rotate it back and forth until the least amount of resistance is felt due to the water flowing past the alignment fin. |
