A permanent clamp-on transit-time flow meter with a 1:2500 turndown, a 16 MB timestamped datalogger and waveform diagnostics. AC or DC powered. Made in Britain.
SKU IC-UPF
You want permanent non-invasive metering with a serious data record and a very wide flow range.
Compare that to the 100:1 on most portables. Turndown is the ratio between the highest and lowest flow a meter can measure credibly, and it decides whether one instrument covers your whole operating envelope or whether you are blind at the bottom of it.
A meter that goes blind at low flow does not tell you it has gone blind. It reports zero, or it reports noise, and both look plausible.
The 4–20 mA answers what is this pipe doing right now. The 16 MB timestamped log answers what has this pipe been doing. When a process engineer asks why the yield dropped last Thursday, the second question is the one that gets answered.
Genuinely unusual on a meter at this price: the IC-UPF can distinguish fluids by their acoustic properties. Water and oil have different speeds of sound, and a meter that measures speed of sound can tell you which one is going past. It is why METRI calls out oil dewatering as an application.
85–265 V AC or 7–24 V DC. This is not field-changeable. The DC option is what makes remote and solar-powered installations possible — get it wrong and you have a mains-only instrument at a site with no mains.
