Abstract
An impact flowmeter includes a housing having an inlet end, an outlet end, and an interior region. The flowmeter also includes an inlet chute coupled to the inlet end of the housing. The inlet chute has an open end for discharging material into the interior region of the housing. The flowmeter further includes a load cell coupled to the housing for generating an output signal, and an impact plate coupled to the load cell. The impact plate is aligned with the inlet chute so that material entering the housing strikes the impact plate. The impact plate deflects the load cell in a measurement direction to change the output signal from the load cell based on the flow rate of material. The flowmeter still further includes a stop for biasing the load cell in the measurement direction to establish a preload condition on the load cell, thereby reducing the affect of vibration on the output signal from the load cell. The flowmeter further includes a load cell mounting bracket located outside the interior region of housing to isolate the load cell from the interior region of the housing. The flowmeter includes a gasket for insulating the load cell from the housing to reduce the effect of ambient vibrations of the housing on the load cell. The impact plate is adjustable vertically and horizontally relative to the inlet chute.
