Dubai, UAE, 26 August 2018: “Continuous flow monitoring for open and closed loop heating and cooling systems, for safe and efficient operation, is always a challenge,” said Val Kesler, Product Manager, Level and Flow, Dwyer Instruments, while highlighting the challenges to flow detection in boilers and chillers in HVAC systems. Explaining further, she said: “Boilers require an adequate flow of water, while chillers require the flow of glycol, for efficient operation. The applications are typically monitored with the use of insertion turbines, but often succumb to long-term frictional wear and tear.” The launch of the Dwyer Insertion Flow Transmitter uses electromagnetic technology, she said, which has no moving parts and hence does not lead to breakage, extending the life of the system.

Elaborating on the technology used by the Insertion Electromagnetic Flow Transmitter, Series IEF, Kesler said: “The flowmeter features electromagnetic technology which accurately measures fluid velocity while providing several continuous signal outputs. The series is specifically designed to offer superior performance paired with simple installation and use.” She added: “One unit is adjustable to fit pipe sizes from 4 to 36” (101.6 to 914.4 mm) on most pipe materials with integrated glycol concentration compensation. It offers several output options, including a selectable BACnet MS/TP or Modbus RTU over 2-wire RS485, as well as a standard analogue, frequency and alarm outputs.” The transmitter, which was launched in December 2017, she said, has been well received by end-users, as the product allows end-users to monitor their resource use and assess their energy consumption, while allowing them to improve their productivity and energy efficiency.

While elaborating on the accuracy of the instrument, she said: “In order to verify accuracy, each unit is calibrated on multiple line sizes so that a technician can easily field set a unit for their specific application. With the help of the many menu options, a technician can accurately measure the wall thickness and circumference while determining the ideal installation depth of the pipe.” She added: “Previously, insertion flow transmitters in the market did not offer flexibility with regard to product configuration. Dwyer addresses this concern, while simplifying the installation process and methods of use.”

While elaborating on the influence the product is likely to have on the HVAC industry, Kestler felt positive and said: “HVAC systems contribute to environmental comfort and air quality. An HVAC system that is shut down, even for a day, can prove detrimental to the comfort and health of a building’s inhabitants. The insertion Electromagnetic Flow Transmitter will maximise energy efficiency and improve productivity, while driving down the cost of running heating and cooling systems.”
