ROUND UP PRESSURE + LEVEL MEASUREMENT
Very ‘smart’ smart water metering
solutions
The accuracy and broad range of Kamstrup’s smart water meter-
ing solutions are attracting significant interest frommunicipali-
ties, utilities, and environmental agencies in South Africa. The
company has continuously nurtured and enhanced the value
of its products to offer customers advanced solutions for a low
total cost of ownership.
Kamstrup’s smart water metering solutions combine the
newest ultrasonic technology with remote reading, advanced
pressure, and leakage surveillance to allow utilities to control
their water distribution systems in previously impossible ways.
The improved solution helps users monitor temperature, pres-
sure, water quality, and water loss in the distribution network.
The superior data quality, consistency, and remote system
configuration capability go a long way in helping utilities make
real-time decisions and optimise operations.
Additionally, the most outstanding feature of Kamstrup’s
meters is their ability to retrieve data with the help of drive-by,
walk-by or fixed infrastructure technology.The technology nei-
ther relies on end users to read the meter, nor requires them to
send the consumption data.When utilities need to collect meter
data, they merely have to drive near the meter’s location. The
data is automatically collected and transferred to the meter data
management system.
The data collected from Kamstrup’s systems are more com-
prehensive than the data from any other type of meter. It con-
tains information about leaks and bursts, as well as the highest
water flow rates, enabling customers to understand their water
consumption levels and patterns and prepare for the future.
Kamstrup’s two modular, multi-communication smart water
meters − the MULTICAL 21 and flowIQ 3100 − are aimed at the
residential and industrial segments, respectively.
Kamstrup’s meters maintain high precision throughout their
lifetimes, even if the flowrate falls. Furthermore, its meters were
tested and approved by the South African Bureau of Standards
(SABS) in 2013, resulting in huge boost to saleability.

Fast and accurate automatic
pressure testing
Fluke , represented locally by Comtest, has just
launched the new Fluke 729 Automatic Pressure Cali-
brator, simplifying the calibration process by automat-
ing pumping to the precise test pressure, improving
calibration integrity by compensating for minor leaks,
and automatically documenting the pressure calibra-
tion process.
With the rugged, portable 729, technicians simply
input a target pressure and the calibrator automati-
cally pumps to the desired set-point while the internal
fine adjustment control stabilises the pressure at the
requested value.
Fluke 729 features
• Automatic pressure generation and control for
multiple tests to 300 psi, (20 bar, 2 MPa). Fill in a
test template and the 729 automatically pumps to
and documents a multiple-point pressure calibra-
tion test
• Easy calibration documentation using defined
templates for transmitters and switches. Input the
starting and ending test pressures and number
of test points and the calibrator documents the
applied pressure, measured mA, and percentage
error for each test point. The bright colour graphi-
cal display flags out of tolerance test results in red
• HART communication enabling mA output trim,
trim to applied values, and pressure zero trim-
ming of HART pressure transmitters. Technicians
can also perform light configuration tasks such as
changing a transmitter tag, measurement units,
and ranging
• Measurement of mA signals on transmitter outputs
and sourcing and simulation of mA signals for
testing IPs and other mA loop devices. It includes
a 24 V loop power supply for testing and powering
transmitters in standalone tests disconnected from
the control system
