(接上期)(四)浮子流量计浮子流量计分为液体流量计和气体流量计。液体流量计可采用容积法、质量法和标准表法检定。气体流量计可采用容积法和标准表法检定。1.液体流量计(1)检定程序1按要求调节流量,使浮子升到预检定流量,待稳定后操作换向器换向,使检定介质流入工作量器; (Continued) (D) Float flow meter Float flow meter is divided into liquid flow meter and gas flow meter. Liquid flowmeter volume method can be used, the quality of law and the standard table test. Gas flowmeter volumetric method and the standard table can be used to test. 1. Liquid flow meter (1) test program 1, according to the requirements of the flow control, the float rose to the pre-test flow, to be stable after the operation commutator commutation, the test medium flow into the workload;
