The invention discloses a device and a method for measuring
solid circulation flow rate, which relate to the
solid transmission technology. The device for measuring
solid circulation flow rate is composed of components, such as a valve, a high-low
stock level switch, a timing device, a material measuring section, a balance
pipe and the like. The position of the material is detected through the high-low
stock level switch, a
signal is transmitted to the timing device, and the material accumulation time is displayed, so that manual
timing error is avoided, and measurement accuracy is improved greatly. The material measuring section of the device provided by the invention can be obtained by directly selecting one section of a dip leg, and the device is simple in structure and convenient to operate. With the balance
pipe, the interference of the measuring process on the
system operation can be reduced, and the device for measuring
solid circulation flow rate is especially suitable for measuring the
solid circulation flow rate of the devices with high
solid circulation flow rate, and also can be used for measuring the solid circulation flow rate under a pressurization condition.
