Cleaning-up project of Panama City and Bay

Cleaning-up project of Panama City and Bay

The cleaning-up project of Panama City and Bay includes: Construction of Health Service networks Construction and rehabilitation of Collectors and Drive lines Interceptor system Plant for wastewater treatment. These elements will be developed to collect, transport and treat wastewater of Panama City which is currently discharged directly into the bay or rivers and streams in […]

FAQ#118 – Is it possible to use the reference reading (zero reading) taken with a digital inclinometer probe as a reference reading for another digital inclinometer probe?

No, this is not possible.Sisgeo calibrates each probe individually, but each probe has its own small different properties, that have a certain influence on the readings. The international standard ISO 18674-3, describing the reference reading, states that:« It is good practice to take an additional reference measurement with an independent probe that can be used as […]

FAQ#111 – Why I cannot read correctly my 4-20mA current loop gauge?

It could be a problem connected to the power supply given by the readout or logger. When the power supply is in the current loop (2-wire gauge) it is necessary to consider the effect of voltage drop across the shunt resistor on the voltage applied to the gauge. For example, suppose a 4-20mA gauge requires […]

Egnatia Odos Road – Athens, Greece

Egnatia Motorway was designed to the specifications of the Trans-European road network. Across Epirus and Northern Greece from Igoumenitsa to Evros, Egnatia Motorway is one of the largest road construction projects in Europe, 670 kilometres long and 24.5 metres wide.The realisation of this motorway requires the construction of: 50 road interchanges; 350 entrance / exit […]

FAQ#073 – Quel est le nombre maximal de capteurs numériques (RS-485, Modbus), le nombre maximal de chaînes et la longueur maximale du câble dans un réseau RS-485?

Last update: October 2021 All the SISGEO digitized sensors utilize a RS485 interface with Modbus protocol. 1.The maximum number of digitized sensors in a RS-485 network are 247 (theoretical) 2.The maximum number of digitized sensors chains that is possible to connect to Modbus master unit (as OMNIAlog or miniOMNIAlog) are 4. 3. About the maximum […]

FAQ#036 – Quel est le bon mélange pour réaliser le coulis d’un tube inclinomètre?

Il n’existe pas de règle stricte pour chaque type de sol. Cela dépend de nombreux facteurs qui peuvent varier dans chaque situation géologique et géotechnique. Dans tous les cas, le coulis utilisé doit avoir un comportement approchant celui du sol, même s’il n’est pas vraiment possible de faire correspondre leurs caractéristiques parfaitement, en particulier si […]

FAQ#032 – Quelle est la méthode de lecture de la nouvelle génération de postes de lecture et enregistreurs Sisgeo pour les instruments à corde vibrante?

For VW sensors Sisgeo has developed automatic algorithms to search for the resonant frequency in case of environmental noise or poor signal. In this way you can distinguish between the natural frequency of the sensor and the frequency of the noise, thereby reducing measurement errors and false alarms. This method also provides improvement in the […]
