Redundant twin measuring system where there is a requirement for increased operational safety for sewage pumping stations (e.g. main pumping station) in building service engineering and for municipal applications. Product features The twin measuring system MWAS-BN uses two mutually independent measuring systems which work in different ways. The analogue sensor AS for integration in the pump control unit is combined with the pneumatic-mechanical contact sensor system MB. If one of the two measuring systems fails, emergency control is automatically triggered by the other measuring system.

Compact control systems with micro-processor technology for controlling STRATE sewage pumping stations with two pumps each and an installed motor rating of up to 5,5 kW per pump. Particularly suitable for building services engineering (twin systems) and do not require a separate control cabinet. Compact control system AWAmaster 2 in plastic housing Ready for connection with 1.5 m cable and CEE plug 16 A, 5-pole Parallel operation of both pumps to cope with increased sewage volume (e.g. during heavy rain) LCD plain text display Thermal and electrical monitoring of the motors Manual – 0 – Automatic functions Pump switch-off through switch-off point with run-on time Acknowledgement button Electronic monitoring of the motor current Forced switch-on, switchover and alternation of pumps Variable graduated start-up (switch-on delay) Internal acoustic alarm Collective fault message potential-free and potential-bound Backwater alarm potential-free

Magnetic-inductive flow measurement allows the precise measurement of electrically conductive liquids such as sewage. Standard measuring values are the current flow and the accumulated pumping capacity (e.g. daily volume). The measuring signals are available either as 4 – 20 mA or impulse signals and can be transmitted to the data recorder for state recording and diagnosis or to the AWAcontrol control technology for pump control. Magnetic-inductive flow meters are reliable and economic compact units or installation in the pressure line and are available in two basic versions: Sensors for pipe installation with integrated measuring transducer and on-site display as a compact unit Sensors for pipe installation with separate measuring transducer. With this version, the measuring transducer can be located separately on the wall in the service building or as a fitted housing directly in the AWAcontrol control cabinet.

2DFmaster AWAcontrol control system for STRATE sewage pumping stations with two pumps each and an installed overall motor rating of 0.75 kW to 75 kW each. Particularly suitable for building services engineering and municipal applications (twin systems), offers outstanding ease of use and functionality of the AWAmaster technology also for pumping capacities over 4 kW. LCD plain text display Thermal and electrical motor monitoring Manual – 0 – Automatic functions Pump switch-off through switch-off point with run-on time Acknowledgement button Electronic monitoring of the motor current Forced switch-on, switchover and alternation of pumps Internal acoustic alarm Collective fault message potential-free and potential-bound Backwater alarm potential-free All settings and fault messages retained after power failure Operating hours counter High resistance to interference Simple operation Level recorded either by internal pressure transducer, external 4 – 20 mA probe or float switch

The compact control system with micro-processor technology for controlling STRATE sewage pumping stations with one pump and an installed motor rating of up to 5,5 kW. Particularly suitable for building services engineering (single systems) and do not require a separate control cabinet. Compact control system AWAmaster 1 in plastic housing Ready for connection with 1.5 m cable and CEE plug 16 A, 5-pole LCD plain text display Thermal and electrical monitoring of the motor Manual – 0 – Automatic function Pump switch-off through time or switch-off point Acknowledgement button Operating hours counter Ammeter Electronic monitoring of the motor current Forced pump switch-on Variable graduated start-up (switch-on delay) Internal acoustic alarm Collective fault message potential-free and potential-bound Flood alarm potential-free All settings and fault messages retained after power failure (battery back-up not required) Reserve inputs for float switch, telecontrol module

Pre-fabricated STRATE AWASTATION service buildings are set up directly on top of shafts (STRATE AWALIFTSCHACHT) or optionally alongside shafts on concrete foundation blocks. Pre-fabricated solutions offer the possibility of housing system components e.g. shaft cabinets, control elements, electric systems and service connection so that they are easily accessible integrating further optional system components e.g. STRATE AWAaerob ventilation systems, operating data recording and remote transmission etc. One-piece pre-fabricated concrete building, suitable for road and crane transport with four threaded attachment and transport sleeves Re-siting of the service building is possible Inside walls: exposed concrete, painted with washable dispersion paint, colour according to customer wishes Outside walls: textured render, painted in colour according to customer wishes Floor: smooth concrete floor plate with openings for shaft cover, cable duct etc.
