旋转活塞式水表 MH・15〜25 ROTARY PISTON WATER METER
用途:记录家庭自来水管道饮用冷水总量。
特点:本表为容积式水表,采用活塞旋转原理, 计量精度高,计数与水隔开,数字清晰,读书方便。
APPLICATION:
Measuring the volume of cold portable water passing through the pipeline.
FEATURES:
Volumetric meter,on principle of piston rotation,accurate measurement ,easy and term clear reading.etc.
MAXIMUM PERMISSIBLE ERROR:
A) in the lower zone form Q1 inclusive up to but excluding Q2 is ±5%
B) in the upper zone form Q2 inclusive up to and including Q4 is ±2%
a) 在从包括较小流量(Q1)在内到不包括分界流量(Q2) 的低区中的较大允许误差为±5%
b) 在从包括分界流量(Q2) 在内到包括过载流量(Q4) 的高区中的较大允许误差为±2%
