2 Introduction Setting the Standard The MagMaster Loflo range, available in sizes 5mm to 6mm ( /2 in. to 24 in.), is designed specifically for use on the many diverse applications encountered in the water and waste-water industry. The specification, features and user benefits offered by this range are based on BB s worldwide experience in this industry and they are all targeted specifically to the industry s requirements. Flow Performance MagMaster Loflo has an extended operating flow range with.25% accuracy over the majority of this extended range in both forward and reverse flow directions as standard. Emphasis is placed on the low-flow region which is particularly important for the water industry. MagMaster Loflo sets new standards for low-flow capability and enables accurate measurement of previously unmetered night flows. Submersible and Buriable ll MagMaster Loflo sensors have a rugged, robust construction to ensure a long, maintenance-free life under the arduous conditions experienced in the Water and Waste Industry. The sensors are, as standard, inherently submersible (IP68, NEM 6P), thus ensuring suitability for installation in chambers and metering pits which are liable to flooding. unique feature of the MagMaster Loflo sensors is that all sizes are buriable. Installation merely involves excavating to the underground pipe, fitting the sensor, cabling back to the transmitter and then backfilling the hole. No metering chambers or pits are required and the overall low-cost installation is simple and fast. Comprehensive Features wide range of features and user benefits are built into MagMaster as standard: bi-directional flow liquid sensing comprehensive test mode universal switch mode power supply (options are available for C and DC supplies) self-diagnostics programmable multiple alarm capability ssured Quality MagMaster is designed and manufactured in accordance with international quality procedures (ISO 9) and all flowmeters are calibrated on nationally-traceable calibration rigs to provide the end-user with complete assurance of both quality and performance of the meter. Fully Featured Transmitters MagMaster is offered with integral or remote transmitters, each being available with a choice of display, configuration and communication options to suit the application. Standard features include forward, reverse and net flow totalizers, flow rate, alarm monitoring and automatic self-diagnostics to ensure integrity. ll data and values are in customer-defined units of measurement. System compatibility is assured with a choice of current, pulse, serial data and Smart HRT communications. MagMaster operating parameters may be set via local keypads, remote configurators or computers as appropriate. The software features multi-level password protection capability to prevent inadvertent programs or settings changes. Data is stored in nonvolatile memory for greater than -year retention. In the non-keypad variant, display data can only be changed using a magnetic wand. No operational parameters can be changed without the use of configurators and appropriate passwords. New Performances Standards for Flow Measurement Widest flow range, optimum accuracy and long term stable calibration mean that sets new performance standards in the water industry. This unique low flow rate capability enables previously unrecordable minimal night flow rates to be metered; particularly important for bulk revenue and district metering applications. 2
