*1 Liquid must allow for the passage of an ultrasonic pulse, as well as not contain large air pockets or excessive bubbles. Readings may become unstable depending on the type of pipe.
*2 When using stainless steel or iron pipes, the ideal pipe wall thickness is as follows, FD-XS1E: approx. 0.5 mm 0.02″, FD-XS8E: approx. 1 mm 0.04″, FD-XS20E: approx. 1 0.04″ to 2 mm 0.08″. FD-X signal strength and stability will decrease as the thickness of the pipe wall increases or decreases from the suggested size.
*3 The zero cut flow rate can be changed in the settings. When using the unit with a low flow rate range, perform an origin adjustment when the fluid is not moving if you change the zero cut flow rate.
*4 The connector part of the sensor head cable is IP65/IP67.
