What’s a reliable margin of error for a flowmeter?
Hello, As part of a campaign to measure flow rates in our wastewater network, we installed a portable Mainstream level/velocity meter. I'd like to be able to define a margin of error expressed as a percentage of the reading. Does anyone have any info on this? Thanks in advance.

Method for carrying out nighttime inspection of a wastewater network?
Recent diagnostics performed on our wastewater network allowed us to identify secondary drainage tanks vulnerable to groundwater infiltration. Conducting a camera inspection of the full length of these units is a priority, but we can't divide them up with other sectors. That is why we are looking at...

What instrumentation do you use to measure bypass volume in a wastewater system?
Hi, We have to equip our bypasses with a device to measure (as opposed to estimate) discharge into the natural environment, knowing there is no acceptable floodgate in the hydraulic sense of the term. What kind of device to you use? For anyone using level/velocity sensors, what feedback do you ha...

do you have any advice for settings on an automatic rainwater/storm water sampler?
Bonjour, I imagine your facility or storm water drainage system is equipped with a flow monitor, in which case the controller settings must be proportional to the measured flow rate so as to sample rain events only.
