Photography for Questa Voce

Questa Voce is a new, large-scale singing group set up to provide a chorus and soloists for concerts and events. They are professionally-trained to the highest standards in all styles of performance and singing including opera, classical, musical theatre, jazz, oratorio and contemporary. Involved in live performance and recording, they are a new force not to be missed.

Our photography was set in an Elizabethan manor house in Dorset; small group shots, entire group and an individual session with each member. The images were first seen in the programme for the group's acclaimed December 2012 performance, Questa Voce sings Christmas.

Groveley Detection: new web app simulates use of Incus ultrasonic gas detectors

Engineers can quickly determine approximately how many Groveley Incus ultrasonic gas leak detectors would be needed to monitor a process area, thanks to a new web app.

   Groveley Detection’s free app allows the user to input plant size, area of coverage, gas pressure, gas temperature and background ultrasonic noise levels. 

   It indicates approximately how many Incus detectors are required to protect a hazardous area under given circumstances. The app is a first step before embarking on an ultrasonic mapping survey to monitor background ultrasonic noise levels and determine optimum positioning of the detectors – which is always advisable when utilising UGLDs.

   Ultrasonic/acoustic gas detectors instantly detect gas leaks by 'hearing' the sound generated by escaping gas, rather than responding to specific measurements of LEL or ppm.

   It is the only commonly-available method of detection able to detect a gas leak without the gas cloud needing to come into direct contact with the detector. The technology is impervious to wind, fog or gas dilution and is therefore very reliable in outdoor installations.
