Berliner-Kindl-Schultheiss-Brewery / Germany

In 2015, the Berliner-Kindl-Schultheiss-Brewery decided to modernize the young beer separator which has three turbidity measuring points (at the inlet, at the outlet, in the bypass). The goal was to incorporate reliable, low-maintenance turbidimeters. Those should guarantee optimum operation of the separator as well as allow a comparison of in-line and laboratory measurements.

SIGRIST turbidimeters TurbiGuard were chosen, with a connection to the control unit SICON M. These instruments supply EBC turbidity values which can be compared with those measured in the laboratory and cover a measuring range of up to 1000 EBC. This ensures smooth operation of the separator particularly during turbidity peaks from fresh fermentation tanks. SIGRIST TurbiGuards hardly need to be serviced.

The Berliner-Kindl-Schultheiss-Brewery was able to significantly reduce maintenance expenses at the separator during the first year.

 

»The SIGRIST instruments function without faults and never cause problems. Moreover I value the many years of personal contact provided by SIGRIST.«

Water

Water supply Bern / Switzerland

In July 2012, the Bern water supply planned to monitor the water from the groundwater well Kiesen (output 30'000 - 40'000 l/min) for turbidity and SAC 254 (UV absorption) using SIGRIST instruments.

In December 2012, the turbidity monitor AquaScat 2 and the absorption measuring instrument ColorPlus 254/700 nm were taken into operation.

The quality of the groundwater is very clean with a constant turbidity of 0.008 FNU. A parallel measurement with a second SIGRIST turbidimeter AquaScat 2, carried out in January 2013, confirmed the very low turbidity value. SIGRIST photometers are capable of handling even such low turbidity values in a reproducible manner.

In July 2015 SIGRIST received a follow-up order by the Bern water supply for three AquaScat 2 WTM-A instruments and one ColorPlus 254/700 nm.

»In addition to the high reliability of the ColorPlus and AquaScat instruments, the customer service provided by SIGRIST is unique!«

Traffic & Environment

Road tunnel Gotthard / Switzerland

Since September 2007, a total of 210 SIGRIST smoke detectors of the type FireGuard are in use in the Gotthard tunnel and its approach tunnels. Together with additional sensors such as linear fire alarm cables, flow measurement devices etc., the smoke detectors are the basis for the early detection of smoke and fire events.

In September 2016, after a period of use of 9 years, Mr. Werner Furrer, head of the Office for the Operation of National Roads (Switzerland), summarized their experience with the FireGuards as follows:

  • On average, there was one event per month, which was detected without fault
  • In a smoke event, the FireGuard is always the fastest system
  • No false alarms owing to correct parameterisation

»We have had no failures so far. SIGRIST FireGuard smoke detectors are very reliable.«
