INSTRUCTIONS

VARIABLES OR MEASUREMENTS REQUIRED : Pressure in (PSI), fluid density in (Kg/m3), you will need to list each existing fitting along the pipeline (number of elbows-tees, valves…). Internal diameter at the end of the pipe in millimeters. Use the period for decimal separator and not the comma.

PROCEDURE : 1st. Enter the density of the fluid, for example 1000 Kg/m3 . 2nd. Enter the initial pressure measurement (PSI) . 3rd Enter the internal diameter of the pipe in millimeters. 4th In pipe length enter the total length of the pipe as a result you will obtain a final flow rate and pressure where the flow rate analyzed from the program is compared with the flow rate measured in situ.

DISPLAY BUTTON : You will obtain a summary of the data obtained that can be preserved by taking a screenshot.

CALIBRATE BUTTON: You will obtain the resulting values for calibration.

RESET BUTTON : Reset to initial values.

CHECK : All measurements can be compared without breaking the pipe by placing a flowmeter or manometer or any other sensor, where the result reflected in the final flow rate will be compared with the measurement of the flowmeter in situ.

A- The FLOW generated by the program is compared with the flow measurement of the flowmeter instrument, if the flow is 15% higher it indicates obstruction, for water flow it could be obstructed by incrusted lime, gas flow could have liquid. For oil or oil derivatives it could be internally oxidized or in case water has been used in the oil pipe it could also present lime incrustations. Whose temperatures would decrease.

B- The FLOW generated by the program is compared with the measurement of the flowmeter instrument, if the flow is 15% lower it indicates the presence of a leak or a widening in any case the temperatures will increase.
