Blow-by flow meter is used for engine dynamometer testing applications. This flow meter is ideal for the measurement of crankcase blow-by gases in engine emissions testing applications. It measures the flow rate of blow-by gases as they flow out of the crankcase vent, which is an effective way to monitor piston-ring sealing, lubricant performance, and crankcase ventilation systems. The advantage of this flow meter includes minimal effect on engine performance during blow by measurement, low-pressure drop and drift-free performance.
Blowdown tanks are used as an alternative system for cooling the bottom boiler blowdown. The function of a blowdown tank allows undesirable discharge from the boiler that is to be discharged directly out of the system. These large tanks retain the blowdown water volume from one blow after the flash steam, which has been vented to the atmosphere and allow the water to cool down by natural convection over 6-12 hour period. The cooled water will be below 140 ° Fahrenheit when it is displaced by the next blowdown and forced out of the overflow drainpipe.
