一、检定复式水表的几个难点目前,国内大部分水表检定站采用的是静态容积式水表检定装置或静态容积式水流量装置。这两种检定装置无法检定复式水表的主要原因有以下几点:1.检定装置中安装被检水表处的台位安装距离小于复式水表的长度和宽度。无法把被检的复式水表安装到检定设备上。2.在用的大口径水表检定装置上没有检定小口径旋翼式水表的配置,没有检定小口径旋翼式水表的瞬时流量显示和小容量的工作量器。
First, the verification of complex water meters several difficulties Currently, most of the domestic water meter verification station is used static volumetric water meter calibration device or static volumetric water flow device. The main reasons why these two kinds of verification devices can not verify the multi-type water meter are the following: 1. The installation position of the water meter to be inspected in the verification device is less than the length and width of the multi-type water meter. Can not be seized on the multi-meter installed on the test equipment. 2. In the use of large-diameter water meter calibration device does not verify the configuration of small-diameter rotor-type water meter, there is no verification of small-diameter rotor-type water meter instantaneous flow display and a small volume of work.
