Introduction：The AVL Leakage Volume Gauge 442S is based on the orifice plate principle and measures the volume of air leakage between the piston and piston ring.
The AVL Air Leakage Gauge 442S is based on the orifice plate principle and measures the volume of air leakage between the piston and the piston ring.AVL has become the worldwide benchmark for air leakage measurements due to its high accuracy.The AVL Air Leakage Gauge 442S can even accurately measure jumping airflows. Therefore, the measuring system is designed to allow measurement of airflow in both directions.
1、a wide range of measurement: AVL air leakage meter 442S by replacing the measuring tube, you can measure from small engines to small single-cylinder engine up to 2000KW engine;
2、the measurement of the average value of high precision: can measure the reverse flow, air leakage in either direction can be measured. This ensures that 442S than other products on the market to measure the accuracy of higher, because of the consideration of all the airflow even in the case of severe airflow jump;
3、insensitive to contamination and low maintenance costs: the use of cushioning systems and specially designed small holes in the condensation when assorted immersion, such as traces of oil or fuel. Therefore maintenance costs are very small;
4、pressure loss is minimized: the system has no impact on engine performance, even when used in closed-loop flow, the piston leakage gauge caused by the pressure loss is very small.
