Flooding, both predicted and sudden, has become an increasingly common phenomenon in recent years. Many suffering localities have been un- or under-prepared, with little reason to believe they were at risk until it was too late. A reliable and cost-effective advance warning system that continuously monitors rivers, storm drains and overflows for rising water levels can save lives and protect property, alerting authorities and communities to impending danger.

The SonicSens 2 battery-powered ultrasonic level and flow sensor, from specialist manufacturer HWM (UK), offers non-contact, accurate, remote and wireless monitoring of water levels and flow rates. The ultrasonic sensor precisely measures the distance to (and therefore level of) the water surface, and can automatically send alerts to up to 16 phone numbers when the level reaches specified thresholds. When an alarm condition activates, it can also provide accelerated dial-in functionality, allowing users to quickly access detailed, relevant and timely new information when they have to.

Noise pollution complaints have risen more than 900 per cent in South West London, as the level of noise from Heathrow Airport has increased exponentially.

Although it was first believed that the increase in noise was down to both runways running simultaneously, it is now believed that a change in weather has caused the amplification of noise.

Some have reported that the noise is being carried over South West London when it was not previously.

a1-cbiss (UK) are the UK’s distributor of the GASTEC gas detector tube systems. The GASTEC tube sampling system is designed to work in a multitude of applications offering a low cost and quick method of gas detection.

The GASTEC pump offers a sleek ergonomic design and has the ability to detect up to 600 gases, vapours and particulates.

The unique colorimetric tube technology displays results in a short time without requiring lab analysis making them the perfect gas detection method for sampling on remote sites and sites that need instant results.

WIKA (Germany) has now completed its portfolio of temperature controllers with two digital instruments for simple thermostat applications: The model SC58 and model SC64 close the gaps in this segment between mechanical products and complex PID instruments.

The new digital controllers are designed for a measuring range of -80 to +400 °C, and can therefore be used universally. The switch hysteresis can be set via the menu, which assists the flexibility. Both two-point controllers are equally notable for their high switching accuracy and contact rating (16 A). They are easy to use and offer a highly-visible display (13 mm high characters).
