北京益都 水表系类 旋翼式立式冷热水表

'北京益都旋翼式立式冷、热水表

一、北京益旋翼式立式冷热水表结构与用途 Structure and Use （1）本水表是用于计量流经管道自来水或中水的体积总体量的流量测量仪表，适用于单向水流的自来水、井水、纯净水、中水等计量，该水表具有流通能力大，压力损益小，读数清晰直观，使用寿命长等特点。

（2）水压不大于1MPa

（3）冷水水温不超过40℃且不低于0℃

（4）热水水温不超过90℃（1）This meter use to measure the mass of volume of tap water through pipe, suit to measure flux tap water, well water, pure water, and intermediate water in single direction. This meter has huge circulation, small pressure lost, clear number show and long work life feature.

（2）The water pressure should under 1MPa

（3） The cold water should under 40℃ and no less than 0℃

（4） The heat water meter should under 90℃ 二、15-40主要技术指标 Main parameter 本表型号

从包括分界流量至包括流量的高区的示值误差限:±2% (一)The temperature of the water can\'t pass 40℃(二)The rated pressure:10Kgf/cm2(98×104Pa)(三)The pressure lost in the water meter in Max flux ≤1Kgf/cm2(98×104Pa)(四)The show number error range form mix flux to the low district:±5%

The show number error range form piding line flux to the high district:±2%注：(1)公称流量是水表在规定误差限内允许长期工作的流量。

(2)始动流量是水表开始连续指示时的流量，此时水表不计示值误差。

(3)最小流量是水表在规定误差内使用的下限流量。低于最小流量时水表不能准确计量。

(4)流量是水表在规定误差限内使用的上限流量。在流量时，水表只能短时间工使用不至损坏。Note:(1)Rated flux is the permitted flux in the long work situation for the water meter.

(2)Beginning flux is the flux at the moment the meter open, and this time, the meter can\'t accout the show error.

(3)The Mix flux is the permitted Mix flux for the meter, if the flux is lower than this number, the meter will not to account correctly.

(4)The Max flux is the highest flux for the meter in the rated error, at the max flux the meter only work in a short time and not to broken.'
