1. How to wire turbine flowmeter
Turbine flow sensor/transmitter (LWGY - □ N type, LWGY - □ A type) 1. Hehui basic type LWGY - □ N type "24V+" (red wire scraping calendar) connected to DC24V positive terminal; Connect the "power supply -" (white wire) to the negative terminal of DC24V; Pulse "(yellow line) is connected to the pulse input terminal of the secondary meter
2. Explosion proof LWGY - □ N type, as shown in Figure 8
3. LWGY - □ A type, as shown in Figure 9.
2. Password for adjusting the K value of Tianjin Schmidt turbine flowmeter
The K value adjustment password for Tianjin Schmidt turbine flowmeter is uniquely set by the manufacturer and cannot be changed or obtained by the user themselves.
. You must directly contact the manufacturer or authorized dealer to apply for the password. 1. The only way to obtain the password is to apply to the official customer service of Tianjin Schmidt or the authorized distributor of your code and purchased product. Manufacturers usually verify your device information (such as model and serial number) and provide the corresponding password. After obtaining the password, the calibration work needs to be carried out by professionals, usually following the following process: - Use the password to enter the calibration mode of the flowmeter. -Connect a standard calibration device (such as a flow standard device using a standard meter method) and introduce a known and stable standard flow value. -Record the delayed or missed flow rate value or pulse frequency displayed by the current flowmeter. -Calculate the new instrument coefficient (where K0 is the original coefficient) using the formula K=K0 × (Q standard/Q display). -Input the calculated_600x400.jpg)
3. Requirements for the use parameters of turbine flow meters:
The use parameters of turbine flow meters must be strictly matched with the characteristics of the medium, working conditions, and installation requirements. The core of the core is to ensure measurement accuracy and instrument life.. 1. Medium adaptation parameters Bi Chan • Liquid medium: viscosity should be ≤ 50mm ²/s, and when it is higher than 5 × 10 ⁻⁶ m ²/s, it must be calibrated with real liquid. Corrosive liquids must be used for instruments made of 316L or Hastelloy materials. • Gas medium: must be clean and dry, with impurities or easily condensable gases requiring the installation of precision filters, and not suitable for dirty media
2. Matching parameters for working conditions • Flow range: Liquid measurement should be maintained within the range of 10% -90%, gas is recommended to be 20% -80%, to avoid low flow rate failure or high flow rate wear. • Pressure and temperature: The working pressure and temperature should not
