Abacus cold mains water meter type Em scaled 0 - 999 litres in steps of 1 litre
Addding a preset quan- tity of water to a mix has long been carried out using pails or hosepipes. Not very accurate and certainly not consistent. Now, Hertfordshire company Aquameter has developed the ABACUS digital water measuring system for dispensing ac- curate preset quantities of water straight into mix-
ing vessels, tanks, etc. Easy to install and simple to use, the ABACUS delivers repeatable results day in, day out, reliably and consistently.
Thousands of units have been sold worldwide to a whole variety of
industries where water is added to powders or granules for mixing
purposes. Just dial in the batch amount required and press the start
button. The unit stops the flow of water when the required quantity has been delivered...... easy!

ADVERTORIALS Spiroflow expands technical sales team
Powder handling and dry solids processing experts, Spiroflow, has expanded its technical sales capability with the appointment of Stephen Bunn as a senior support engineer. The new role reports into Chris Brennan, technical sales manager, and will be based at the firm’s headquarters in Clitheroe, Lancs. A professional engineer, Stephen has worked in the powder handling industry for nearly 30 years, his previous engineering positions have been with compo- nent manufacturer, DMN-Westinghouse, where he provided solu- tions to companies handling powder and granular materials and Flomat Ltd where he managed large contracts to supply materials
handling equipment to major companies globally, designing equipment to meet client’s specific applications. Spiroflow views the role as being key in bridging the gap between sales and design engineers. By having technical expertise at the front end, providing technical information and drawings to accompany sales quotations, the company believe that they will be able to avoid any potential misinterpretation in meeting customers’ requirements.

DISTRIBUTOR, SWITCHTEC has extended its range of Climate Control Compo- nents used to manage and control the environment within Control Panels. Control panel manufactures know too well that all electrical and elec- tronic components generate heat, and this heat needs to be controlled to ensure efficient panel design and performance. Excessive temperatures, at least, cause components to operate inefficiently or, at most, shorten their lifespan and increase component failures. Fluctuations in temperatures can also bring the added complication of condensation and moisture in- side a Control Panel which can be extremely detrimental to any electrical device installed inside.
To ensure optimal panel performance Switchtec has a range of Panel Ventilation products which include Fan-and-Filter units, available in 5 frame sizes from 114x114mm, 36m3/h airflow to 325x325mm, 920m3/h airflow. The units are a quick snap fit, low profile, design with an Ingress protection of IP54 and available in RAL7035.

New, BFX3 Compact clamp-on Flow meters and Heat meters for liquid measurement
Quick and easy to install, even by non-trained operators, the clam- shell design of this range makes them a fast and reliable solution for non-invasive flow and/or heat measurement applications. As the sensor separation distance is fixed, there is no need for adjustment and once fitted they are not easily dis- turbed.
Clamp on ultrasonic flow meters are ideal for applications when system shut down is not feasible. These flow meters are non-intrusive and simply clamp on to the outside of the pipe without making contact with the inter- nal fluid. They measure the time it takes for an ultrasonic signal transmitted, from one sensor to the other.
The sound's "time of flight" is accurately measured in both directions and the difference in time of flight calculated. The liquid velocity (V) inside the pipe can be related to the difference in time of flight (dt) through the fol- lowing equation: V = K * D * dt, where K is a constant and D is the distance between the transducers
Features:
• BFX3 Flow models and BEX3 Heat Meter versions • DN15 to DN90 (9 models) • 24V DC Powered
• 4-20mA Output and optional Pulse Output, Alarm Outputs • Modbus RS485 Communications
• No need for tubes of ultrasonic grease, rulers and marker pens. • Clean, hassle-free installation
• Pre-configured or In-Field adjustment possible • Suitable for various pipe material: Copper, Plastic, Steel, Iron and Stainless Steel
• No moving parts or contact with the fluid JANUARY JUNE 2021 | PROCESS & CONTROL 55
• Suitable for aggressive liquids • Zero pressure loss imposed by this design • Can be relocated
• Data logging and remote monitoring options available
These budget friendly clamp-on flow meters utilise the ultrasonic flow measurement method ensuring quick and simple installation without the need to cut into existing pipe-work. It is not necessary to turn off the supply of water/liquid to install the product. It is also possible to supply this model with GPRS/GSM Data logging and remote access via cloud server. Ultrasonic flow meters are now widely used in the industrial and building sectors. Their simplicity and reliability has seen their widespread adoption throughout the world as an accurate and reliable method of quantifying liquid flow rate measurement and consumption. These flow meters can be used on a variety of pipe sizes or material, are non-invasive and therefore not prone to the levels of deterioration that are seen by in- trusive flow meters.
