Advancements made to one of the world’s most commonly used flow meters will dramatically improve fluid flow measurement readings across a wide range of industries. Venturi flow meters are used extensively in the measurement of gas and other low viscosity fluids, such as hot water, solvents and fuels, and are a proven technology due to their ease of use and robustness.
A team of flow and temperature measurement experts at McMenon Engineering Services, based in Cumbria, have now adapted the existing technology to improve the accuracy of measurement readings of high viscosity fluids, for example bitumen, glycerin and syrup, to be used across more sectors, including drilling, heavy fuel oil and even food and drink. The McMenon team has devised the High Viscosity Venturi, a hard wearing device which can withstand higher viscosity fluid applications, to improve the performance of readings, while also removing the need for calibration - potentially up to 50% of the cost of the device.

CIAT’s high-performance ClimaCIAT air handling units (AHUs) are fully compliant with the updated National Health Service (NHS) code of
practice on ventilation in hospitals. The new NHS specification, set out in Health Technical Memorandum 03-01 (HTM-03-01), was published earlier this year following input from industry and healthcare estate specialists.
The code is designed to ensure ventilation equipment installed in hospitals meets the demanding health and safety, environmental, reliability and resilience requirements of high- quality healthcare applications. One of the most important additions is the requirement to
Trane
Trane, a leading global provider of indoor comfort solutions and services and a brand of Trane Technologies, continues on the “Electrification of Heating” pathway and today expanded its heating solutions portfolio with new Trane Exergy Series heat pumps. The Exergy Series units deliver heating capacity of up to 120 degrees Celsius and can replace oil and gas boilers in industrial process, buildings and district heating applications.
The Trane Exergy heat pumps deliver highest temperature of the generated heat on the market, and can source energy from natural water as well as wastewater or industrial processes, at a temperature range between -20 degrees Celsius and +45 degrees Celsius. This gives customers the operational flexibility and widens the scope of applications, where this energy can be recovered, extracted and used as a source for efficient and environmentally responsible heating. The new Trane Exergy Series heat pumps are manufactured in cooperation with Oilon, Finnish energy and cleantech company with over 60 years of experience in generating heat for private residences, large residential buildings, district heating networks, and for a variety of industrial processes.
The new Trane Exergy Series heat pumps are available in capacities between 30 to 2000 kW and feature the near-zero global warming potential (GWP) R-1234ze refrigerant. X

provide covered access for staff while servicing AHUs located outdoors on a rooftop or on the ground. This ensures staff and equipment are protected from weather and the possibility of water ingress while access panels are removed during maintenance.
To address this, CIAT developed a weatherproof enclosure
made of galvanised steel that runs alongside the unit, providing complete protection from the elements during servicing work, and preventing dirt and moisture from entering the unit to minimise contamination risks. To reduce environmental impact, the guidance specifies that components, such as bypass dampers and related gears, must not be made of plastics. CIAT has developed alternative solutions made of steel that perform just as effectively without reliance on single-use plastics. In a further design refinement, CIAT has developed a drain
pan made of stainless steel, which is easier to clean and helps maintain hygiene. The design also helps minimise the overall height of the unit. Effective management of condensate water is another focus of the guidance, in order to minimise the risk of legionella and other sources of contamination. “To this end, drain pipework on ClimaCIAT units for hospitals is fitted with specialist glass (borosilicate) u-bends, enabling service staff to easily see any build-up of deposits by a quick visual inspection.
