HydrINS 2 / HydrINS 2 Mini Flow Meter
Installation Manual
Page 6/73
1Introduction
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.
The measurement scale is from 2 cm/s to 5 cm/s and the relative measurement accuracy is +/-2% or
+/-2 mm/s, 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 HydrINS2 Mini, covering diameters
from 70 mm to more than 2000 mm.
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, but only for the HydrINS 2 Mini).
HydrINS 2 and HydrINS 2 Mini electromagnetic insertion flow meters can operate in several different
configurations:
Connected to a standalone data logger with a digital input channel
(records data on site): Lolog, Vista +
Connected to a standalone data logger with a digital input channel
with communications capability (records data remotely): Octopus LX
Connected to a Display A, blue (possibility of a Pulse output to a
remote management system)
Connected to a Display C, green (possibility of a Pulse or 4-20 mA
output to a remote management system)
Two measurement positions are used for continuous flow measurement:
The position at the centre of the pipe, position representing the maximum speed
The position at one eighth of the diameter, a position representing the average speed
The velocity 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.

1.1 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.

The flow value is obtained via the following processing chain:

1.2 Environmental and safety conditions
Optimum use of the HydrINS 2 flow meter requires a suitable measurement environment in order to
avoid as far as possible any environmental disturbances that could affect the measurement.
Hydreka shall not be held liable for the quality of the measurements performed using the HydrINS
2/HydrINS 2 Mini flow meter if the recommendations given below are not observed.
1.3 Conditions in the measurement environment
Protection: IP 68 (NEMA 6): resistance to submersion within the limits of the
standard
Operating temperature range: -20°C to +60°C
Storage temperature range: -20°C to +70℃
Measured velocity Vm
= A × Fi × Fp × Vm
Where:
Q: flow rate
A: internal cross-section (calculated by Winfluid software from the inside diameter,
ID)
Fi: insertion factor (calculated by the Winfluid software)
Fp: profile factor (calculated by the Winfluid software)
Vm: measured velocity

1.4 Software environment
The HydrINS 2 and HydrINS 2 Mini and Displays A and C are configurable using Winfluid and Winfluid
Mobile software, developed by Hydreka.
1.5 Safety
THE CONDUCTIVITY OF THE WATER PASSING THROUGH THE PIPE
MUST BE GREATER THAN 20µS/cm.
Minimum software version: Winfluid 2.98 or Winfluid Mobile 1.98
: The physical installation of the HydrINS 2/HydrINS 2 Mini
probe is a potentially hazardous operation. 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
WARNING: 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.

Figure 3: Safety chain
The safety chain is also used to ensure that the probe is fully raised when the flow meter is
withdrawn. It is connected to a hook that can pivot around the probe.
1.6 Product transport
The HydrINS 2 / HydrINS 2 Mini flow meters are delivered in an appropriate box with polystyrene
blocks to protect them during transport.
