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 Enquiries:Tel. +27 (0) 10 595 1821 or email sales@comtest.co.za
