1. Flow measurement: advanced method and good performance. Pressure-difference method can be used to measure impulse velocity, flow testing just use this same principle. It offers good simulation of the transformer internal faults.
2. High precision, with error correction device
3. High automation
4. LCD display, light and portable, easy to carry
