District Heating, Modelling Consumption and Efficiency

Twelve BFU Ultrasonic Heat Flow meters from Bell flow Systems are being used in a district heating study being undertaken as part of a Southampton University PHD Thesis.
 
Installed in Halls of residence at various locations across the University campus district heating grid the BFU range was chosen for its low cost and non-invasive installation requirements, whereby the products flow and temperature sensors are clamped externally onto the heating pipes, rather than plumbed in using the traditional method.

 BFU-100-M
 
Using time-of-flight acoustic technology, the BFU measures velocity and flow rates whilst integrating them with supply and return temperatures within the heating circuit, to calculate the amount of thermal energy used at each location. The results are logged via multiple outputs available from the unit including, Modbus Comms, 4-20mA analogue signal and scalable pulse output.

GWR200 Flow Sensor from APG

Image
Bell Flow Systems are pleased to introduce the new GWR200 flow sensor from APG, which promises to take the problems and frustration out of your level measurement. The Systems True Echo™ Communication Tool, which provides a Modbus-to-USB connection for communication with True Echo™ Software allows for advanced configuration and monitoring of multiple True Echo™ sensors. Specifications includes an auto calibration for easy setup with the True Echo™ software, a robust IP65 ingress protection housing, innovative signal processing and disturbance signal suppression and featuring a range up to 10 feet with SS rod, 80 feet with cable. Additionally, the sensors are unaffected by foam, vapours or dust. The Sensor NEMA 6 housing comes as standard, and its 316 SS or PFTE-coated 316 SS probes can operate in process temperatures from -40° to 203°C. Robust and reliable, the GWR200 sensor makes difficult level measurements easy. With a programmable 4-20 mA or RS-485 Modbus outputs, and innovativ...

Badger Meter Vision 3000 Turbine Meter

Image
WRAS approved Vision Turbine Meter 3000 Badger Meters Vision series of turbine flow meters have been examined, tested and found to comply with the requirements of The Water Regulations Advisory Scheme which is also known as WRAS. The low cost turbine meters from the Vision series are well known on the market. A new addition to the series is the Vision 3000. The Vision 3000 is a good choice for applications ranging from 2 to 60 l/min. It is great for the exact measurement of small quantities of liquid as well as measuring low flow rates. The Vision 3000 turbine flow meter is entirely made out of Trogamid which is low-priced, transparent and ultra-light. All materials used are compliant with the requirements of the drinking water approval.The product can be used with a variety of liquids such as water, fuels, ink and weak acids and is resistant to ethanol and methanol. The meter has an accuracy of ±3% of actual flow. The Vision 3000 is available in DN12 in G 3/4" and N...
