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:
Connected to a
standalone recorder
with a
digital input channel
(records data on site): Lolog, Vista +
Connected to a
standalone recorder
with a
digital input channel with
communications capability
(records data remotely): Octopus LX
Connected to a
Display,
(possibility of a Pulse or 4-20 mA output to a
remote management system or data transfer via the GSM network).
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
).
