50W1F-H50A1A10B7AW德国E+H电磁流量计代理
50W3H-H50A1A10A7AW,50W1F-H50A1A10B7AW:德国E+H恩格斯豪50W3HH50A1A10A7AW,50W1F-H50A1A10B7AW,E+H电磁流量计在污水处理中就会用到:
1进水管;
2初沉池到贮泥池泥量检测;
3污泥泵房剩余、污泥流量检测;
4污泥泵房回流污泥流量检测;
5二沉池配水井的出水流量检测;
6消化池进泥量检测;
7消化池出泥量检测;
8絮凝池药剂进量检测等等。
E+H流量计比对的方法与标准表校准法
流量计比对的方法与标准表校准法相似,应在足够长的时间内比较标准表积算总量‰和被校表积算总量V。
1.用皮托管或其它插入式电磁流量计的请参照IS03966用皮托管比对大口径电磁流量计流量值,这样就必须在流量计上游(或下游)适当位置预留插入皮托管或其他插入式流量计的孔或阀。
2.用超声流量计现在较多用可移动夹装式超声流量计(即便携式超声流量计)作流量比对。若电磁流量传感器装于地下仪表井时,应在仪表井内电磁流量传感器上游(或下游)预留夹装超声换能器所需管段和空问。若是新建管线则在未装流量传感器之前,精确测量拟装夹装式超声换能器管段的内径,并记录在案,计算准确的流通面积,以便比对时应用。内径测量方法可参照JJG640J94《差压式流量计检定规程》。
