STRATE TECHNOLOGIE FÜR ABWASSER GMBH

Redundant twin measuring system where there is a requirement for increased operational safety for sewage pumping stations (e.g. main pumping station) for municipal applications. Product features The twin measuring system HWAS-BN uses two mutually independent measuring systems which work in different ways. The analogue sensor HWAS 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.

Closed pneumatic-mechanical switching system The sewage-resistant pressure bellows and the end membrane are connected via a pneumatic line routed in a protective tube. There is a plastic housing on the collecting tank of the sewage pumping station which contains 4 easily accessible micro-switches In addition, there is a manometer for continual filling level display located in the housing

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.

The recording of operating data such as flow volumes, pumping pressure, operating hours and power consumption of the pumps etc. is essential for the state monitoring of – usually municipal – pumping stations and pressure line as well as for the diagnosis of machine components. Data recording system with LCD display for the electronic acquisition, display, recording, evaluation, remote transmission and archiving of up to 6 analogue and digital input signals. Product features For daily, monthly, annual evaluation; meter statuses, operating times and volumes; min., max. and mean value recording Multi-colour display, digital, bar chart and graph representation Archiving in the internal memory and on compact flash card (no data lost in the event of a power failure!) Remote data transmission via standardised interfaces Suitable for door installation in the AWAcontrol control cabinet

Alarm messages can be signalled optically and acoustically at the pumping station or transmitted remotely by mobile phone or phone line. Optical and acoustic alarm in 12 V DC technology for connection to the alarm unit AG 230/12. Product features Multi-tone series combined with xenon flash 32 different tones can be set Volume adjustable up to 105 dB Optical and acoustic signals can be triggered separately

Mains-independent alarm unit for signalling a fault. Product features Powered by integrated 1.8 Ah 12 V battery in the event of a power failure Optical and acoustic alarm issued via external alarm AM 14 Additional optical display of alarm message using LED in the alarm unit Signalling through potential-free output Reset button for acknowledging fault message

A GSM modem is a favourable option for transmitting plain text fault messages as text messages to operating staff‘s mobile phones for immediate notification of fault messages. The output of the message text can be freely configured. Text messages can be transmitted to several mobile numbers. A sufficiently good mobile phone network is required for the use of the GSM modem; alternatively an automatic telephone dialler can be used where a landline connection is available. Transmission of fault messages by text message and the mobile phone network. Product features Automatic alarm issued as text message when changes in state occur Freely definable message texts Cyclic alarm forwarding to up to 5 different numbers Analogue and/or digital inputs Straightforward configuration with PC and software Text message state query for all inputs and outputs Remote access with PC/laptop and status display on the screen

If mobile phone reception is poor and there is a landline connection available, the automatic telephone dialler is a reliable alternative to fault message transmission by text message. Any fault messages are forwarded to different pre-programmed phone numbers. Product features For forwarding fault messages via the landline. Integrated microphone and control loudspeaker Voice messages to any number of recipients Digital message to one or more alarm receiving systems Remote query, remote control depending on device type Messages to pager or as text message depending on device type

The system comprises two electrodes which are installed above the floor of the pumping station shaft and which issue an alarm message via the connected level relay when they come into contact with water. A sudden water leak in the shaft is detected immediately thus effectively preventing damage. Product features Level relay with connection terminals for potential-free messages for installation in the AWAcontrol control cabinet

Due to their special design, 100 % free passage and low flow resistance, STRATE AWASTOP non-return valves are ideal for: Sewage technology, media with solids and coarse solids, sludge (up to 5 % TM) Fresh and service water technology, including in areas where high pressure losses make powerful pumps necessary On request: pumping of fluids deviating from the media listed Areas where quiet operation is particularly important Non-return valves are recognised all over the world as for universal applications in the pumping of fresh water, effluent, sludge and air. Stand for high operational safety Stand out thanks to their excellent value-for-money and low maintenance requirements 100 % free passage Low flow resistance Quiet operation thanks to the inclined valve seat which shortens the closing distance Minimum clogging tendency through optimum hydraulic design− Fail-safe closing of the valve since the closing element is fixed securely into the valve cover
