Viewing measurements by display or recording
The flow data measured can be used in different ways:
Archived by a data recorder that supports a
digital channel
(Lolog, Vista +, Octopus LX, etc.)
or by an external system (SCADA or remote management)
Displayed on a display unit
Displayed on a Display and archived by an external recorder
Displayed and recorded by a Display recording unit
The displays show:
The flow rates (positive and negative)
The mean/instantaneous speed
The total normal/inverse/net volumes
Alarms
There are some noteworthy differences between the two display units:
With a Display A: The display unit can be equipped with batteries to obtain 10 years of
operating life. Two pulse outputs are available.
With a Display G and recording unit: Data are recorded and can be sent via the GSM network.
Two pulse outputs are available, with optional external power supply.
With a Display C: External 20-36 V DC power supply (from Serial Number 41754; if below,
then: 20-28 volts) with two 4-20 mA outputs (on terminal block) and four pulse outputs (two
on terminal block, two on output connector).
The HydrINS 2/HydrINS 2 Mini flow meter operates in two separate modes:
Mode 1 (without Display): The flow meter operates in standalone mode thanks to two
batteries in the head of the flow meter.
Mode 2 (with Display): The flow meter operates thanks to the power supply from the display.
A back-up battery is kept in the head of the flow meter. In the event of an interruption of the
electrical power supply from the display, this battery allows pulses proportional to the flow
rate to be sent until a normal electrical power supply is restored (except for Display C).
