Engineers working on a project in North Wales have employed novel techniques to improve wastewater treatment efficiency, reportedly at a fraction of the cost of traditional methods, saving an estimated £3.5 million. Alison Miles from NIVUS, an instrumentation partner in the project, explains the flow measurement technology behind the reported improvements. ...
Small wastewater treatment works (WwTWs) frequently present significant physical challenges for instrumentation and control engineers. However, a compliant flow measurement facility has been installed at a plant in Fowey, in the south-west of England, by a partnership involving a water company, a contractor, an instrumentation provider and an inspection company. The flow monitor at Fowey WwTW ...
The ranges of thermal mass flow meters for gases are specified in such units as ln/min, sccm or m3n/h. These units look like volumetric units, but in truth they are expressions of Mass Flow. What is the story behind this? ...
Ultrasonic flowmeter mainly consists of flowmeter body, ultrasonic transducer and its installation parts, signal processing unit and flow computer components. For on-site contact and clamp-on flowmeter, the pipe where the transducer is installed can be used as the meter body, the transducer of the contact flowmeter is directly in contact with the measured fluid, ...
Noise influencing factors In the ultrasonic flow meter measurement system, there are many pipeline systems involved, such as valves, rectifiers, and other types of flow-blocking pipes. ...
Data storage redundancy technology Electromagnetic flowmeter normal operation requires flow calibration value, cumulative flow value and flowmeter information and many other parameters. ...
The Role of Flow Measurement Flow measurement serves as the backbone of effective water management. ...
In today's highly competitive process industry, continuous optimization of operations and service work is crucial. Moreover, as environmental regulations pertaining to flaring become increasingly stringent, it becomes imperative to employ reliable and efficient flow measurement solutions. For over 30 years, ultrasonic flow meters have been utilized to measure flow to flare stacks. However, flare ...
Instead, simplifications must be introduced, which are rather significant, to have a chance of computing a solution in a reasonable time with reasonable computer hardware. ...
The filter station, the heart of the System, consists of filters, flow meters and sensors, and automatic valves and controls to effectively manage and monitor the subsurface drip irrigation System. ...
Flow meter accuracy is critical for process control but can be hampered by upstream and downstream flow disturbers. This problem may be addressed during the design process, though in some circumstances it’s impossible to eliminate disturbers. What Are Flow Disturbers? Anything that impedes flow upstream or downstream of a flow meter is a flow disturber. This includes piping ...
Important accessory benefits include a low flow selfaspirating concentric nebulizer with inert liquid flow path, a heated inert spray chamber and membrane desolvator with adjustable temperatures for optimum sample transport efficiency, and dedicated mass flow controllers with computer software control for Ar sweep and N2 ...
Thermal Mass Flow Meters Optimize Air Flows to Aeration Basins Up to 60% of the energy used by wastewater treatment plants is from the aeration process. ...
Operators must comply with operating specifications. The production flow includes computer controlled cutting, computer controlled rolling, submerged arc welding, assembly, nondestructive testing, heat treatment, hydraulic test pressure, blasting, and paint. ...
The complex electrical and mechanical system requires power and signal wiring between the flow meter, the pressure transmitter, the temperature transmitter and the flow computer. ...
Because long straight pipe runs are difficult to find in these installations, varying flow profiles within the pipe degrade measurement accuracy. Furthermore, both the orifice and the turbine meter measure only volumetric flow. Additional pressure, temperature, and differential pressure sensors as well as a flow computer are ...
Municipalities need precise mass flow measurement instrumentation to bubble the exact amount of air into these aeration basins for the bacteria to flourish. SIERRA’S SOLUTION In the 1980’s, many municipalities used differential pressure (dP) devices to measure the mass flow rate of air delivered to their aeration basins, but these devices proved to ...
The landfill gas is sampled (using a chemical cell) and the CO2 content is analyzed and a mini computer uses this compositional data to correct the flow rate. In general, while biogas composition does change over time, it doesn’t change that quickly. ...
This vortex mass flow device directly measures three parameters. Then, it computes seven more properties of liquids, gases, and steam. ...
The ability to measure gas flow more accurately with sub-metering based on a new technology, can result in substantial savings. ...
