This paper determines the scale factor for an electromagnetic groundwater flowmeter using an air-cored square pancake coil as the electromagnet. It also proposes the use of an array of electrodes to provide a better estimate of the average water spee

A return-to-zero, bipolar, trapezoidal current generator for driving the coil of a prototype electromagnetic groundwater flowmeter is described. Operation of the circuit, which employs a laboratory DC power source, a MOSFET H-bridge, some ancillary c

The signals measured by electromagnetic flowmeters are corrupted by 1/f noise from the electrodes and interference from changing electric and magnetic fields when driving the electromagnet. The effect of this interference can be mitigated using syste

Nutrients leaching through groundwater are one contributor to waterway contamination. Guiding land use decisions to reduce the impact on water resources requires accurate knowledge of the flow of groundwater. Currently, measurements from monitored we

Fluorescent tubes have long been the mainstay of lighting for many premises, due to relatively high efficiency and long life. LED efficiencies are set to exceed those of fluorescent tubes, with dimming and controllable colour rendering readily achiev
