1.BURKERT涡轮流量计的通气和停气要求。通气顺序:保证流量计后端的阀门处于关闭状态;再缓慢开启流量计前端的阀门,确保升压速度≤35KPa/S;后缓慢开启流量计后端的阀门,使其从小流量下运行直至调节至需要值。整个过程保持有压启动。停气顺序:先缓慢关闭流量计后端阀门;再缓慢关闭流量计前端阀门。
2.防止长时间超量运行。超流量运行会严重影响使用寿命,降低计量精度,导致误差增大;(注意观察表头工况流量百分比不宜长时间超百分百)瞬时流量:从瞬时流量的观察,结合用户当时用气情况判断是否有小火不走,大火超量程现象。
3.注意温度、压力的数值。误差主要集中在压力、温度的检测精度两方面,在发现流量、温度、压力值与实际偏差较大或示值不稳定时,或与以前经验数值存在较大偏差时,要及时处理。

INLINE sensor-fitting with paddle
wheel for flow measurement
The sensor-fitting S030 has a built-in paddle
wheel to measure the flow rate. When liquid
flows through the pipe, the paddle wheel is set
in rotation producing pulses which frequency is
proportio
nal to the flow rate.
The Bürkert ”INLINE Quarter-turn” technology
is a co
nstruction ensuring a leakage free
operation.
The paddle wheel rotation (permanent magnets
included in the wheels) is detected co
ntactless
through the sensor-fitting wall. The transmitter
can be snapped-on or removed without opening
the pipe or interrupting the process.
