HYDREKA - Model ChronoFLO 2 - Flow Meter
From Flowmeters
The HYDREKA ChronoFLO 2 flow meter uses the principle of measuring ultrasonic wave transit times to measure flow, and therefore does not intrude on pipe systems under charge. The ChronoFlo flow meter is housed in a waterproof case, with military-type connectors. As standard, it has 2*4-20 mA intputs, 2*on/off outputs (alarms, sampling or connection to SCADA systems), an external power supply input and a USB connection (data recovery and program duplicating).
The flow meter is equipped with a data recorder th...
The flow meter is equipped with a data recorder that can record up to 1,000,000 values, which can be processed with spreadsheet, and can operate in full standalone mode for up to 1 month.
The flow meter is usable for both treatment (water and sludge) and drinking water. Its applications include checking fixed station flow meters (DEM, etc.), analysing raising pumps, diagnosis, etc.
It is compatible with all our sampler range and is an essential tool for authorities such as SATESE, SATEP, BE, etc.
Applications
The ChronoFLO® 2 transit time flowmeter can measure instantaneous flow rates in your flow-carrying pipes. This instrument uses a fully coded signal correlation process to obtain stable measurements even under the most challenging conditions. To cover a wide range of applications in any sector, only one signal processing unit is used. This configuration is supplied with two sensors and a mounting rail that fits a wide range of diameters.
ChronoFLO 2 is used for the fo llowi ng applications:
- Diagnosis of drinking water and waste water networks,
- DMA (leak detection monitoring),
- Checking existing flowmeters,
- Calibration of lift pumps,
- Volume quantification.

Two ultrasound pulses are emitted by the sensors, which act alternately as transmitters and receivers:
- One pulse in the direction of fluid flow (t2),
- The other pulse in the opposite direction of the fluid flow (t^.
The mean velocity of the fluid is obtained from the difference in transit times At = (t2 -tj.
The flow rate is automatically deduced according to the internal cross-section of the pip
