Z Method
The signal transmitted in a Z method installation has less attenuation than a signal transmitted with the V method
When the pipes are too large, there are some suspended solid in the fluid, or the scaling and liner are too thick.
This is because the Z method utilizes a directly transmitted (rather than reflected) signaling which transverses the
liquid only once. The Z method is able to measure on pipe diameters ranging from 100mm to 5000mm (4 inch to
200 inch) approximately. Therefore, we recommend the Z method for pipe diameters over 300mm (12 inch).

Transducer Mounting Inspection
Check to see if the transducer is installed properly and if there is an accurate and strong enough ultrasonic signal
