D371x butterfly valve weight table d371x butterfly valve weight is different due to different pressures and specifications. Now let's introduce the weight of d371x butterfly valve under the pressure of PN1.0, PN1.6 and PN2.0 from dn50 to dn600

2、 Problems of fluid conductivity
The decrease of fluid conductivity will increase the output impedance of the electrode, and the error will be caused by the load effect caused by the input impedance of the converter. Therefore, the lower limit of fluid conductivity in the application of electromagnetic flowmeter is specified according to the following principles.
