Abstract:
A liquid circulator includes an upstream tank having a first pressure sensor, an intermediate tank, a downstream tank having a second pressure sensor, a circulation route for circulating liquid through an liquid ejecting head, the downstream tank, the intermediate tank, and the upstream tank, a first pump on the circulation route between the intermediate tank and the upstream tank, a second pump on the circulation route between the downstream tank and the intermediate tank, a first drive circuit configured to apply a first driving pulse to the first pump, a second drive circuit configured to apply a second driving pulse to the second pump, a controlling unit configured to calculate a pressure fluctuation value of the circulation route based on pressure values measured by the first and second pressure sensors, and adjust a phase difference between the first and second driving pulses as to minimize the pressure fluctuation value.

Claim (Index 14):
The liquid ejector according to  claim 9 , further comprising:\n a first diaphragm at a liquid surface of the upstream tank; and a second diaphragm at a liquid surface of the downstream tank, wherein the first pressure sensor measures the pressure value inside the upstream tank above the first diaphragm, and the second pressure sensor measures the pressure value inside the downstream tank above the second diaphragm.
