2 Introduction
The HydrINS 2/ HydrINS 2 Mini electromagnetic insertion flow meter is intended to measure flow in
pipes carrying drinking water or raw water. The probe performs a velocity measurement and
calculates the flow rate by integrating the velocity over the flow cross-section.
ACS certification and WRAS-certified materials.
The measurement scale is from 2 cm/s to 5 m/s (0.787 inches to 16.4 feet) and the relative
measurement accuracy is +/-2% or +/-2 mm/s (0.0787 inches), where the error applied is the larger
of the two.
The HYDREKA range of electromagnetic insertion flow meters comprises the HydrINS 2, which comes
in five standard lengths (300, 500, 700, and 1000 mm) and the HydrINS 2 Mini, covering diameters
from 70 mm (2.75 in) to more than 2000 mm (78.74 in).
Flow meters are installed using a 1" BSP or NPT insert collar equipped with a ball valve (also possible
using a 3/4" BSP or NPT collar for the HydrINS 2 Mini).
HydrINS 2 and HydrINS 2 Mini electromagnetic insertion flow meters can operate in several different
configurations:
Two measurement positions are used for flow measurement:
The position at the centre of the pipe, which represents the maximum speed position
The position at one eighth of the diameter, which represents the mean speed position
The sensor of the HydrINS 2/HydrINS 2 Mini flow meter can be inserted in different positions across
the cross-section of the pipe. This allows a flow velocity profile to be created in order to refine the
mean speed calculation and therefore also the flow measurement. A set of default parameters is
available in the Winfluid software (refer to the HydrINS 2 / HydrINS 2 Mini Flow Meter Programming Manual).
All Catalogue Numbers for the products presented in this manual are listed in Appendix 3.

2.1 Measurement Principle
The velocity measurement principle is based on the application of Faraday's Law, which states that a
voltage is generated by the movement of a conductor through a magnetic field.
In the case of HydrINS 2/HydrINS 2 Mini, the magnetic field is generated by a coil at the end of the
probe, and the water passing through the pipe, whose conductivity must be at least 20 µS/cm,
represents the conductor.
The electromotive force generated by the passage of the water through the magnetic field,
comparable to a voltage, is measured by the two electrodes, which are visible on both sides of the
stem. Because this electromotive force is proportional to the velocity, the HydrINS 2/ HydrINS 2 Mini
probe carries out a velocity measurement derived from the electromotive force of the water. The
flow rate is then deduced from this velocity measurement.
The electromagnetic sensor is located at the tip of the insertion rod. It has an exciter coil and two
electrodes, seen on the side of the sensor.

: A danger arises during the physical installation of the
HydrINS 2/HydrINS 2 Mini probe. Because of the intrusive nature of
the procedure, the probe can be ejected if there is excessive
pressure inside the pipe. The probe is supplied with a safety chain,
which must be used. Ensure compliance with the installation
conditions (pumps shut off, wait for night-time conditions before
installing, etc.).
ENSURE THAT THE CHAIN IS OPERATIONAL BEFORE OPENING THE
INSERT VALVE
PROPERTY DAMAGE CAUSED BY EJECTION OF THE PROBE IS NOT
UNDER ANY CIRCUMSTANCES COVERED BY THE GUARANTEE
THE CONDUCTIVITY OF THE WATER PASSING THROUGH THE PIPE
MUST BE GREATER THAN 20µS/cm.
NOTE: It is essential to avoid sites where the pipes vibrate. If the
probe vibrates excessively after installation, the measurement will
not be correct. In this case, remove the probe.

4.2 Velocity limits for measurement
Maximum velocities must be observed in order to prevent irreversible damage to the sensor. The
following charts show the maximum velocity applicable to the probe according to the chosen sensor
diameter and position. These values are provided as an indication. They are used when programming
the flow meter in Winfluid in the form of the maximum flow rate tolerated by the probe (refer to
the HydrINS 2 / HydrINS 2 Mini flow meter acquisition programming manual)
The flow rate is calculated based on a perfectly developed flow profile. Refer to the ISO 7145-1982
standard.
Figure 11: Maximum velocity for different pipe internal diameters
The creation of a velocity profile is used to refine the insertion factor and profile factor values (refer
to the HydrINS 2 / HydrINS 2 Mini flow meter acquisition programming manual). The order of
magnitude of the maximum velocities to be observed are indicated on the chart below.

4.4 Typical installation of HydrINS 2 / HydrINS 2 Mini flow meters
Typical installations are as follows:
HydrINS 2: 1" insertion – drill 25 mm (0.98 inches) at least
HydrINS 2 Mini: two possibilities:
o Either 1" insertion plus 1"-3/4" adapter – drill 25 mm (0.98 inches) minimum: this
can measure the inside diameter of pipes using diameter gauges marketed by
HYDREKA and adaptable to 1" tappings.
o Or 3/4" insertion – drill 19 mm (0.75 inches) minimum: does not need an adapter.
The preparation of an insertion point compatible with HydrINS 2 or HydrINS 2 Mini is exactly the
same as for the preparation of a classic insertion point for the installation of a connection. No
additional accessories are required. After drilling the pipe, tighten the HydrINS 2 /HydrINS 2 Mini
probe to the ball valve.

4.5 Inside diameter measurement gauges
Before the probe is installed, measurements may be performed using an adaptable diameter gauge
on a 1" insertion thread. Their use requires the appropriate clearance above the pipe.
Figure 14: View of the different components of the diameter gauge
The diameter gauge has a bleed screw to evacuate the pressure. This is useful when excessive
pressure prevents the user from bringing the gauge down to the bottom of the pipe.
Figure 15: Gauge pressure evacuator
Note that a gauge can be created with a personalised size and thread (please ask us). Available gauge
models and their sizes are described in detail in Appendix 2.

5.3 Aligning the guide bar with the direction of flow
After adjusting the insertion distance and placing the flow meter in the desired position, tighten the
cable gland to maintain the position. The orientation of the HydrINS 2/ HydrINS 2 Mini flow meter
must now be adjusted. The head of the HydrINS 2 / HydrINS 2 Mini flow meter has a red arrow to
orient the flow meter in the main direction of flow. Flow in this direction will count as positive, whilst
flow in the reverse direction will count as negative.
Figure 17: Position of the positive direction arrow on the probe head
The guide bar supplied with the flow meter allows the electrodes to be positioned in the direction of
flow. Insert the bar in its lodging in the flow meter head, and then match the arrow with the positive
direction using the guide bar by placing it in the direction of flow.
Once the direction and alignment have been adjusted, tighten the cable gland more tightly to hold
the flow meter firmly in its final measurement position.

The HydrINS 2 / HydrINS 2 Mini insertion flow meter has a Quickfit connector to measure the
pressure at the same point as the flow measurement.
This channel can be connected to a recorder with an internal pressure channel (10 or 20 bars). This
applies to Lolog, Vista +,Octopus LX and other recorders.

7 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 &E 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).

NOTE: This point is essential before putting the unit in operation. If an
incorrect operating mode is selected, the probe electronic board could
suffer irreversible electrical damage.
Figure 20: Installation configurations for HydrINS 2 / HydrINS 2 Mini
It is essential to ensure that the HydrINS 2 / HydrINS 2 Mini flow meter is configured in the
appropriate operating mode before placing it in operation; otherwise, the probe will suffer
irreversible damage (see paragraph 8.2).
8 Installation of a display
It is necessary to check in advance that the HydrINS 2/HydrINS 2 Mini flow meter is configured in
Mode 2 (see paragraph 8.23). It is important to specify that there is always the possibility of
communicating with the flow meter from a computer to perform checks or acquisition
reprogramming because the display is 'transparent' in communication between the computer and
the HydrINS 2 / HydrINS 2 Mini flow meter.
8.1 Preview of Displays
The Displays have cable gland fittings and/or military connectors and/or a TNC connector.
To reduce energy consumption, the display is activated manually using a magnet included with the
Display. This magnet must be applied to the area represented by the symbol
on one of the sides of the housing (Figure 22), to activate the Display. The display time is
adjustable when programming the probe.

: An aerial can also be placed under the cast iron plate, but
remember that there is a risk of knocking the aerial off each time the
port is opened. This installation is recommended for occasional
measurements.
8.11.2 Installing Display G & E and the external antenna
This can be installed inside a chamber or, because it is watertight, on the outside in a protective
casing or in a building. The device shall be positioned according to site accessibility and the
surrounding environmental conditions. For countries with a harsh winter climate, it is best to place
the device underground (deep enough to be protected from the cold) or in a building.
According to the type of installation envisaged, several types of aerial are available. It is essential to
make a careful installation method in order to guarantee good data transmission subsequently. The
quality of the signal level (value from 0 to 31) must be verified for each site, and the measured value
must be greater than 7 for data transmission by SMS, or greater than 12 if data is being sent via
GPRS.
There are three possible aerial installation cases:
Aerial outside in a protective casing:
This type of installation has the major advantage of providing a high signal level, ensuring better data
transmission. The aerial can also be positioned on a mast or pole near the port, whilst installing the
HydrINS display logger inside the port.
Aerial in a port/valve chamber:
This installation can be created with a half-wave aerial or a dipole aerial, because both have a
magnetic base. Because each site has different characteristics, a signal level test must be carried out
with the port closed. In the event of a negative result, try a different aerial position.

Aerial
HydrINS display logger in a port/valve chamber and aerial buried in asphalt:
Figure 40 : Aerial buried under asphalt
This installation should be considered for permanent CPU or long-term measurements. Once the
aerial is set in asphalt or epoxy adhesive, it can no longer be retrieved. This installation can however
be a useful alternative if placing the aerial inside the port does not produce satisfactory results.
