1. Adjustment coefficient of turbine flowmeter

The instrument coefficient adjustment of turbine flowmeter is the core link to ensure its measurement accuracy, usually requiring the use of standard equipment calibration and parameter modification through hardware or software. 1. Coefficient meaning: The instrument coefficient of a turbine flowmeter represents the number of pulses generated per unit volume of fluid passing through it, usually measured in times per liter or times per cubic meter. This value is closely related to the mechanical structure, fluid properties, and pipeline installation conditions of the flowmeter, and is the basic calibration parameter for flow calculation.

2. Adjustment method: Hardware adjustment: Some conventional models are achieved through physical adjustment, such as using a tool to rotate and turn an internal potentiometer to change the resistance value, and adjust the pulse output frequency accordingly.

. This type of operation requires professional personnel to avoid accidental contact with precision components. Software adjustment: Contemporary intelligent flow meters mostly support digital settings, which can be accessed through the surface cleaning hand board button or connected to a computer programmer to enter the parameter menu and directly input the calibrated new coefficient value and save it.

3. Operation steps: First, prepare the standard flow detection equipment (such as the volumetric method calibration device) and parallel the flow meter to be calibrated; Subsequently, multiple testing points were selected within the 20% -100% flow range, and the measured flow values of the standard equipment and the number of turbine flow meter pulses were sync

hronously recorded; According to the formula K=N/V, calculate the coefficients for each point. If the data dispersion is small, take the arithmetic mean. If the difference is significant, set the coefficients in sections; Finally, write the final coefficient value into the flowmeter system. 4. Precautions: During the calibration process, ensure that the fluid properties (density, viscosity, etc.) are consistent with the actual operating conditions to avoid errors caused by medium differences. Before operation, it is necessary to consult the instruction manual of the corresponding model, strictly follow the standardized procedures, and prevent improper operation from causing equipment failure or data distortion.

2. Electromagnetic flowmeter passive pulse output, what is this passive pulse output? Please explain. _Baidu Knowledge Passive means that no external power supply is required. The pulse output type flowmeter you mentioned should be an electromagnetic flowmeter that uses a turbine in Nago. The working principle and process are roughly as follows: a turbine is placed at the center of the pipeline, and when the fluid passes through the pipeline, it impacts the turbine blades, causing the turbine to rotate. The rotational angular velocity of the turbine is proportional to the fluid flow velocity, and the flow rate of the bridge fluid passing through the pipeline can be calculated. The rotational speed of the turbine is detected by a sensing coil installed outside the casing. When the turbine blades cut the magnetic field lines generated by the permanent magnetic steel inside the casing, the magnetic flux in the sensing coil changes periodically. The periodic variation of the magnetic flux causes the periodic v
