Water velocity probe consists of a protected water turbo prop positive displacement sensor probe with a retractable handle connected to form the handle end of a digital readout display. Synthesis of the average flow rate of water flow meter, providing the most accurate flow measurement. Flow Probe is ideal for storm water runoff studies, sewer flow measurements, measuring the flow rate of rivers and streams, monitor water flow rate ditches and pipes. Turbo - propeller velocity sensor probe combined with unique turbo - propeller sensor, using the most accurate positive displacement technology for velocity sensing. Turbo - propeller design debris can be removed, and in a 2-inch diameter casing is protected. Probe housing bottom of the pipe can be placed directly or riverbed, the minimum depth of 2 inches can measure low flow rates. Flow meter blades rotatably on the bearing, so that no mechanical connection to minimize friction. Blade tip through the water inside the magnetic flow meter handle pickup point, generating electrical pulses transmitted by the internal cables to the monitor readings. Turboprop can easily be removed for cleaning or replacement. Flow rate of water flow speed of the computer receives the electrical signals from the computer propeller, the amplified signal is converted to readings ft / sec (or m / s, based on programming). Large LCD screen displays the average, minimum and maximum water flow rate readings. Water velocity computer can store up to 30 groups of minimum, maximum and average data readings. Analysis of these data can be viewed on a computer screen. Water velocity computer with a waterproof shell, four buttons are used to change the function and reset the monitor. Water velocity computer with battery, can be used continuously for about five years, with a low battery alarm display. Flow velocity sensor probe handle retractable handle, length FP111: 1.1-1.8m; FP211: 1.7-4.6m; FP311: 0.76-1.7m. Constituted by anodized aluminum handle, light weight, long life. 4.6m long FP211 velocity probe can measure the flow rate from road drains, streams flow velocity measurements from a low bridge. The FP311 0.76m length contraction velocity probe, to facilitate the flow rate to the remote monitoring of the area. Handle a 0.9 m measuring tape (FP311 to 0.5m) with polyester coating (0.01 feet and centimeter scale) is attached to the lower water velocity probe handle for instant water depth measurements and precise positioning of the turbine. The true average velocity velocity probes can be used to really mean flow velocity measurement ditches. In the water, the computer will average water flow rate as long as turboprop sensor. Obtaining a second reading, and displays the average continuous flow velocities. To obtain the true average velocity, the flow rate of the probe slowly moves over the cross section to be measured. Once the reading is stable, that is, to get the true average water velocity cross section. It is possible to accurately measure the flow rate, it has been appeared in the waves of the entire flow cross-section of different flow rates are averaged. The average flow rate can press SAVE button to save for later review. Optional rotating probe rotating turbine rotating probes can be ± 90 ° from the standard position. This option allows the flow probe on the area is difficult to measure flow velocity measurements, vertical pipe or drainage systems, swimming pool water container. When selecting the right straight fins can be measured parallel to the direction of flow of the water does not flow velocity, will produce significant errors. When the water depth or turbidity due to unable to see the end of the probe, the collimation flap helps directional velocity probe velocity probe parallel to the flow direction. When used, the flow rate of the probe is immersed in water, and the rotation around the probe, until you feel due to the flow resistance through the collimator fins cause minimal so far.
