How to read the UPVC float flowmeter used for constant water volume in wastewater treatment? Is the upper or lower end of the float facing ..

Like all rotor flow meters (i.e. float flow meters): the reading is based on the scale of the flow meter corresponding to the tangent of the upper end face of the middle rotor.

The reading of the virtual sub flowmeter in the floating section is the position where the maximum cross-sectional area of the float is read.. As shown in the diagram, the front burner:

4. What standard is the float reading of the glass tube flowmeter based on?

The float reading of the glass tube flowmeter follows the four calibration standards of position, medium, unit, and temperature and pressure. The reading needs to be positioned according to the shape of the float and adjusted according to the actual working conditions. 1. Reading positioning rules: The shape of the float directly affects the corresponding position of the scale: • Circular float: Take the glass tube scale corresponding to the geometric centerline of the maximum diameter of the float body • Conical float (such as a rotor flowmeter): Read the scale line pointed by the tip of the cone, and the accurate value is when the horizontal tangent of the tip is level with the scale line. 2 The key points for confirming the unit system are that the flow meter glass tube is usually marked with L/h (liters/hour) or m ³/h (cubic meters/hour). The unit: - Before reading, the unit identification next to the instrument label or scale should be cl

early defined to prevent misreading. - The gas flow meter section uses NL/h (standard liters/hour), representing the flow rate under standard conditions (0 ℃, 1atm) Compensation for medium characteristics: The difference in physical properties between the actual fluid and the calibration cars hungry medium needs to be corrected. Reading: - Liquid measurement: When the density deviation exceeds 5%, convert according to the formula Qactual=Qreading × √ (ρ standard closed calibration/ρ actual) (ρ is the density of the medium) - Gas measurement: In addition to density, viscosity influence coefficient also needs to be considered, which can be adjusted through the correction curve table provided by the manufacturer Temperature and pressure parameter compensation fluid volume is affected by the working environment: - Liquid medium: If the temperature change exceeds ± 5 ℃, the expansion coefficient needs to be corrected. For example, diesel expands by about 0.75% in volume every 10 ℃. - Gas medium: Temperature and pressure compensation must be carried out. The general formula is Q standard=Q measurement × (P measurement/P standard) × (T standard/T measurement) (P: absolute pressure, T: thermodynamic temperature). During on-site operation, it is recommended to cooperate with vertical installation to detect rubber joints (pipeline inclination ≤ 2 °) and instantaneous flow stability observation method (value taken when float fluctuation value<5%), which can improve measurement accuracy by 15% -30%.
