LFY-244 Water Filtration Degree Measuring Instrument

Main application
Suitable for the determination of the water filtration performance of papermaking polyester forming nets and dry nets.
Determination principle
Adjust the water pressure to 1500 Pa, allowing water to flow through the overflow pipe into the water tank. Open the baffle while timing. Measure the time it takes for the water to fill a container of a specific capacity, and then convert it to the time it takes for 5 liters of water to flow through a ￠20mm net (with the paper side facing up), which is the water filtration performance, s/5l.
