SOLID APPLIED TECHNOLOGIES LTD (SolidAT)

WHY MONITOR RIVERS and WATER RESERVOIRS?

  • How much sewage is discharged from the factory into the municipal sewer system?
  • How much wastewater is entering the treatment plant via a Parshall flume?
  • Need to measure water flowing in open channel irrigation canals?
  • Need open channel flow for river and other waterway flows?

WHY ULTRASONIC LEVEL SENSORS

Ultrasonic level sensors are continuous, non-contact sensors with no moving parts. Ultrasonic level sensors measure level of clear water and wastewater mixed with solids. Sensors are robust, exhibiting long lifetime and require minimal maintenance. For flow applications, sensors are installed above flumes including parshall flumes, weirs, open canals, waterways or sewers. Ultrasonic technology is the best choice for measuring water and wastewater. Not for flow in closed pipes under pressure..

FLUMES, WEIRS and MANNING

Wide range of flumes and weirs are supported: Parshall, Palmer Bowlus, Khafagi Venturi, Leopold Lagco, H-flume, V-Notch, Trapezoidal Cipolletti, Rectangular Contracted and Suppressed weirs. Complex structures are implemented by formula or a 32-point LEVEL-vs-FLOW mapping table. Flow measurement in canals is based on Manning Formula. The technique is also applicable for flow measurement in open channels such as waterways and underground sewers where no flumes or weirs are possible.

OUTPUT, VOLUME, RELAYS and DESIGN

SolidAT level sensors support analog 4-20mA, digital RS485, USB, HART or Modbus. For remote channel monitoring, select GaugerGSM, transmitting GSM cellular reports with GaugerNET, a web-based monitoring application. Some level sensors support volume flow (totalization). Some level sensors support a set of relays for local control functions (gates, pumps). Sensors are available in a simple compact-form above the open channel or a cabled-sensor where the control unit is separate from the sensor.
