S-type pitot tube flowmeter

S-type Pitot tube flowmeter an S-type Pitot tube flowmeter technology parameters: L type Pitot tube coefficient from 0.99 to 1.01, 0.81 to 0.86, the S-type coefficient between 2 measuring air flow rate is less than 40m / s measuring water flow rate does not exceed 25m / s II. S-type Pitot tube flowmeter uses in scientific research, production, education, environmental protection and decontamination room, mine ventilation, energy management department, commonly Pitot tube measurement pipeline wind, the air velocity in the kiln flue, after conversion to determine traffic measuring the speed of the water flow within the pipeline. With the pitot tube velocimetry and determine the flow of reliable theoretical basis, easy to use, accurate, is a classic of a wide range of measurement methods. In addition, it can also be used to measure the pressure of the fluid. S type Pitot tube flowmeter structure: standard pitot tubes two different inner diameter of the tube sockets made of concentric inner tube straight terminal tail joints is the total pressure tube, the outer tube through the side of the connector is static tube, S-type skin hosted with two of the same diameter pipe welded face airflow the total pressure side, his back to the air flow static pressure end and the joints marked coefficient number and static pressure connector tag number, can not pick the wrong use. Side pointing to the rod with the probe in the same direction, can be used to determine the direction, to ensure that the probe aligned to flow direction S-type Pitot tube flowmeter to use: To properly select the section of the measuring point, to ensure that the measuring point in the smooth airflow straight pipe. For this reason, the measurement of the local members of the cross-section from the elbow, adjustable shaped tube to the flow direction is greater than four times the diameter of the pipe. Local elbow away from the downstream direction, adjustable structure should be greater than 2 times the diameter of the pipe. 2 measurements should be the total pressure hole aligned with the direction of airflow, to point to the lever directions. Measurement points insertion hole should avoid air leakage, and prevent the cross-section on the airflow interference. Can only be measured with a pitot tube to a point of the pipe cross-sectional flow velocity, due to the uneven distribution of cross-sectional flow, and therefore the cross-section should be more measured points, in order to obtain the average. 3 test before using unimpeded. Small static pressure holes often check, not allow impurities clogging holes timely clean inside and outside the tube, in order to ensure the long-term good condition. 4 standard pitot tube test cycle of five years. Use: S Type Pitot tube perpendicular to the pipe placed, compared with the L-type pitot tube, S-type pitot tube placed more sensitive to S-type can also be aiming to halt. There is no need to distinguish between the S-type hosted two Legs, but pay attention to the windward Leg differential pressure gauge "+" pressure port is connected to another Leg with a differential pressure gauge "-" pressure connected to the interface.
