1. How to adjust parameters of flow meter

Flow meter parameter adjustment operation process: Equipment: Flow meter

1. In the initial interface, you can right-click to enter the system settings menu, enter the password, press the light up left button to confirm and enter the settings system.

2、 After entering the system, you can see that there are instantaneous flow parameters in the settings menu, which can be adjusted by moving up and down and pressing the right button to enter.

3、 When entering the second level menu of instantaneous flow setting parameters and scroll width, find the scale flow setting and use the up and down keys to prepare for movement. Right click to enter the scale flow setting menu.

4、 After entering the scale flow setting item, you can set the scale flow, which is the method for modifying the range of the electromagnetic flowmeter. The function of the flowmeter is fully digital processing, with strong anti-interference ability, reliable measurement, high accuracy, and a flow measurement range of up to 1500:1. Ultra low EMI switching power supply, suitable for a wide range of power supply voltage changes, with good EMI resistance performance. Adopting a 16 bit embedded microprocessor, it has fast computing speed, high accuracy, programmable low-frequency rectangular wave excitation, improved stability of flow measurement, and low power consumption. Using SMD devices and surface mount technology, the circuit has high reliability.

2. CE certification standards for flow meters

The CE certification standards for flow meters vary depending on the specific type. Gas turbine flow meters must comply with the EN12261 standard, while electromagnetic flow m

eters must comply with the Low Voltage Directive (LVD), Electromagnetic Compatibility Directive (EMC), RoHS Directive, and MID Directive (if used for measurement), and must meet relevant coordination standards.

. The specific explanation is as follows: The CE certification standard for gas turbine flowmeters is mainly based on the EN12261 standard. The core significance of this standard is to ensure that products comply with the essential requirements specified in European directives, and to obtain a pass to enter the EU market through conformity assessment procedures or manufacturers declaration of conformity. Compliance requirements: Gas turbine flow meters that have not passed CE certification are not allowed to be sold in the EU market and must be affixed with the CE mark before entering. Violation consequences: If the market finds products that do not meet the requirements, they will be ordered to be recalled; Persistent violators may be restricted or banned from entering the EU market, or even forced to withdraw. The CE certification standard for electromagnetic flowmeters requires compliance with multiple EU directives and coordinated standards, as follows: Core Directive: Low Voltage Directive (LVD 2014/35/EU): Ensure the safety of equipment within the rated voltage range. Electromagnetic Compatibility Directive (EMC 2014/30/EU): Limits electromagnetic interference to ensure the normal operation of equipment in electromagnetic environments. RoHS Directive (2011/65/EU): Restrictions on the use of hazardous substances such as lead, mercury, etc., in compliance with environmental requirements. MID Directive (2014/32/EU, if used for measurement): Ensuring compliance with legal measurement standards for accuracy, r
