HydraClam® Water Quality Monitor

Source: Siemens Industry, Inc. - Water Technologies

The HydraClam® Water Quality Monitor is a purpose-built system for the online monitoring of water quality in the distribution system. It measures four key water quality parameters: turbidity (from 0.1 to 10 NTU), pressure (0 to 145 PSI), conductivity (0 to 2500 µS) and temperature (32 to 86°F). The unit is used for targeted water monitoring within identified problem areas or as a fixed-place monitor

•Datasheet: HydraClam® Water Quality Monitor

Made of lightweight corrosion-resistant aluminum, the purpose-built HydraClam device is easy to install. The unit can be fitted underground to certain European hydrants. Alternatively, a mounting adapter can be used to truncate the main for hydrants in other countries. This low profile installation is less susceptible to tampering and provides increased security. For additional water supply safeguards, an internal non-return valve allows water to only flow out of the unit and not in. The fire department can easily remove and replace the device from fitted hydrants.

To ensure that a "fresh" water sample is analyzed, the onboard controller purges the system of water into the hydrant chamber before taking measurements. The data is then stored on the internal data logger from which it is downloaded to a handheld PDA. Up to 8,760 time and date recordings can be stored within a non-volatile Flash memory for all four measurement criteria. The battery-operated unit is readily transportable and requires no specialist skills to install or operate.

The Hydraclam® water quality monitor is also available with remote communications. The unit fits directly onto standard water hydrants with an adjustable aerial that is fitted just below the chamber lid. Data is recorded internally and is transmitted via GPRS / GSM technology to a central data base which can be accessed via a secure web based interface from any computer connected to the internet. The frequency of the update is typically 4 times per day. Data can also be accessed by direct connection to a Palm® PDA or a PC. In addition to viewing the data online, it is possible to export the data directly to a PC in MS Excel format. The data can then be stored locally and distributed to additional personnel.
