Global Water Flow Probe Hand-held Flowmeter

Description

Global Water Flow Probe Hand-held Flowmeter True velocity averaging provides outstanding accuracy! Ideal for storm run-off studies or flow measurings of rivers, streams, canals, and sewers. Incorporates true velocity averaging for the most accurate measurement possible. The probe shaft is available in lengths that extend from 3 feets to 6 feets and from 5 feets to 15 feets. Located on the bottom tip is a protected Turbo-Prop sensor which uses the most advanced positive displacement technique available. For minimal friction, this 2 Inches Turbo-Prop sensor rotates freely on a bearing shaft with no mechanical interconnections. Magnetic material in the propeller passes a pickup coil in the housing producing electrical impulses. These electrical impulses are then carried by wire to a readout display on top of the handle. This readout display amplifies and converts the signal into feet/meters per second readings. Instantaneous velocity and true average velocity are then displayed. A unique two-button keypad allows other functions to be displayed including minimum/maximum velocity, time-of-day, timer, totalizer for batch flows, and RPM for accurate low velocity measurement. Features a 30-record memory, padded gun-type carrying case, five-year long life battery for readout display (no battery required for Turbo-Prop), and low battery indicator. Probe can be extended up to 25 feets with standard PVC pipe and electrical extension cable. Specifications Range: 0.3 to 19.9 FPS (0.1 to 6.1 MPS). Accuracy: average velocity +/- 0.1 FPS. Averaging: true digital running average. Display: LCD. Sensor Type: protected Turbo-Prop propeller with electromagnetic pickup. Weight: 2 lbs. Size: probe expands from 3 feets to 6 feets or from 5 feets to 15 feets (depending on model), sensor housing is 2 Inches in dia. x 3 Inches L. Materials: PVC handle and propeller housing, anodized aluminum shaft, stainless steel bearing. Operating temperature: -4 degree F to 158 degree F (-20 degree C to 70 degree C).
