To provide a metering device capable of performing high precision measurement, using a plurality of load detection sensors of a tuning fork vibration system.

The metering device includes the plurality of load detection sensors with built-in tuning fork vibrators. One of the load detection sensors is set as a master 60, and each of the rest is set as a slave 70. The slave 70 constantly updates a metered value calculated on the basis of the period of the built-in tuning fork vibrator, and continuously outputs the updated metered value to the master 60. The master 60 adds the metered value calculated, on the basis of the period of the built-in tuning fork vibrator and the latest metered value received from the slave 70, and outputs it to a display. The updated data (metered values) obtained by the plurality of load detection sensors with built-in tuning fork vibrators can be summed by using a simple method, so that high-accuracymetering becomes possible.
