Siris - Effluent Flow Reference Targets

It is not acceptable to rely on an empty chamber or channel floor as the base may not be level. In addition due to surface water tension the gauge zero cannot be determined with sufficient accuracy by reading the head gauge with water in the channel drawn down to the apparent crest level.

All SIRIS open channel effluent flow measurement systems are provided with a fixed or removable calibration plate and, on commission, our SIRIS engineers correctly reference the “True Gauge Zero”.

Fixed or removable calibration plates can be provided.
