Running cost is unsuitable for the detection of pipe network tip, and electrode method chlorine residue needs PH and temperature-compensating, thus chlorine residue, PH and temperature this
Three indexs need to measure simultaneously.It can in addition contain increase the parameters such as electrical conductivity.The water sample that electrode method chlorine residue requirement is relatively stablized is
Measurement accuracy is can guarantee that, so most important with its supporting flow cell.Used flow cell is divided to two kinds in the market,
A kind of is the cylindrical type of bottom in and top out, and bubble is easily accumulated using this structure sensor measuring surface, and water requirement is big.It is another
Kind be the flow cell with independent froth breaking path, be characterized at circulation in have two or more passages, water sample is from the
When one passage rises, bubble is overflowed, and then water sample flows downward from another passage by gravity again, and electrode, which is arranged on to decline, to be led to
Need to communicate with air above road, this flow cell, so not closed.And actual hydraulic pressure, especially pipe network water pressure are that have fluctuation
, not closed system easily causes water shortage or overflow.In addition, existing flow cell is general just for chlorine residue electrode itself,
Need taking extra installation method for temperature and PH.Pipeline connection is more when using, and during two flow cell series connection,
Pressure and flow velocity mutually have an impact, and are easily caused water sample unsteady flow, influence measurement accuracy.
