CAPILLARY TYPE DIGITAL VISCOMETER

摘要

PURPOSE: A capillary type digital viscometer is provided to calculate an absolute viscosity at a reference temperature of a specific liquid by having a temperature correcting function regardless of a measurement temperature. CONSTITUTION: A capillary type digital viscometer comprises a fluid discharging unit(50), a body, a first pressure sensor(71), a second pressure sensor(73), a temperature sensor(75), and a controlling unit. The fluid discharging unit charges fluid for measuring viscosity and forcibly discharges the fluid. The body comprises a driving unit for driving the fluid discharging unit. The first pressure sensor measures the inner pressure in the inside of the fluid discharging unit. The second pressure sensor measures the pressure of a portion where the fluid is discharged. The temperature sensor is installed in the fluid discharging unit, thereby detecting the temperature of the fluid. The controlling unit detects the discharging time of the fluid charged to a fluid pipe, thereby calculating the viscosity of the fluid at the temperature detected by the temperature sensor and detect viscosity of the fluid at a reference temperature based on the viscosity of the detecting temperature.
