A mesofluidic scale digital is disclosed. The mesofluidic scale digital includes a valve body including a bore aligned along a longitudinal axis, a solenoid disposed substantially adjacent to the valve body and extending along the longitudinal axis, a poppet carried within the bore and configured to translate a fixed distance in response to a magnetic field generated by the solenoid, an orifice carried within valve body and configured to cooperate with the poppet in response to the magnetic field generated by the solenoid, a bias element carried within the valve body and configured to encourage the poppet to engage the orifice to form a seal, a control element in communication with the solenoid, wherein the control element is configured to: energize the solenoid to generate the magnetic field and translate the poppet the fixed distance away from the seal, and maintain the solenoid in an energized state for a fixed period of time to provide a desired flow rate.
