US 2026/0014535 A1 · DEVICE AND METHOD FOR METERING FLUID

Abstract

Proposed is a fluid metering device including a mixer receiving fluid in a storage tank, a metering tank metering and supplying the fluid to the mixer, a first transfer device transferring the fluid from the storage tank to the metering tank, a second transfer device transferring an input of the metered fluid to the mixer, a sensor measuring a fluid mass in the metering tank, and a controller stopping the first transfer device and activating the second transfer device with the initial remaining fluid greater than the input, and allowing the second transfer device to transfer the amount of input from the metering tank to the mixer, based on the fluid mass from the sensor and preset first and second metering set values, so that it is possible to quickly input a desired amount of fluid step by step, and to precisely adjust a fluid input into a final process.

Dependent claims

A fluid metering device comprising:

a mixer supplied with fluid in a storage tank;
a metering tank metering the fluid supplied from the storage tank and supplying the fluid to the mixer;
a first transfer device transferring the fluid from the storage tank to the metering tank;
a second transfer device transferring an amount of input of the metered fluid from the metering tank to the mixer;
a sensor installed at the metering tank and measuring a fluid mass of the fluid stored in the metering tank;
and
a controller, wherein when an amount of initial remaining fluid in the metering tank is greater than the amount of input, the controller stops the first transfer device and activates the second transfer device, and controls the second transfer device so that the second transfer device transfers the amount of input from the metering tank to the mixer, based on the fluid mass received from the sensor and preset first and second metering set values.

4 more elements

A fluid metering control method comprising:

primarily transferring, by a first transfer device, fluid in a storage tank to a metering tank;
primarily stopping the first transfer device when an amount of initial remaining fluid in the metering tank is greater than an amount of input transferred from the metering tank to a mixer, thereby stopping the transferring of the fluid from the storage tank to the metering tank;
measuring, by a sensor installed at the metering tank, a fluid mass of the fluid stored in the metering tank;
and
secondarily transferring, by a second transfer device, the amount of input from the metering tank to the mixer, based on the fluid mass received from the sensor, and preset first and second metering set values.
