Automatic Water Level Controller (AWLC)

Automatic Water take aim Controller (AWLC)Automatic Water Level Controller (AWLC) will automatically START the pump set as soon as the water aim falls below the predetermined level (usually kept half or 2/3rd armored combat vehicle) and shall SWITCH OFF the pump set as soon as ice chest is full or water level in the lower tank is at below minimum level.AWLC provides you the flexibility to decide for yourself the water levels for operations of pump set in upper/lower tanks.Built in Indications for showing Full, Empty Levels in Upper Tank and lower Tank Empty Indication.MANUAL operation belabor for special operations like watering the plants from pump set.The AWLC ensure no overflows or dry running of pump there by saves electricity and water.Low AC Voltage sensing circuit to stave off polarization of electrodes in water (requires very rare cleaning of electrode ends). Provided with special stainless steel semiconducting electrodes.Consume very little energy, ideal for continuo us operation.Water Level SensorThis water level sensor is conducive for liquids that have a conductivity of equal to or more than 25m Siemens. It is your best choice for a water level switch. The system is economical to install as no special demarcation is required for signal transmission. The level investigate and the evaluation unit can be connected using a long cable. The AC is provided on the probe for preventing electrode deterioration. You can choose from among a variety of level authorization and installation systems such asTwo point sensors for fissiparous switching and automatic control of pump.Four point switching with two pump control logic.Three point switching two for pump control logic and one independent point with or without a settable delay (for probe covered or uncovered).A variety of probes is available for your specific process.ApplicationsThe SLW series water level switches hit to maintain a constant water level avoiding material wastage in your process pla nt. Common applications also include switching pumps on and off to avoid overflow, dry running and indicating water level in an empty tank to avoid wear and tear and production stoppage. Many of our customers in the Food, Power, Chemicals, Sugar, Detergent, Steel, Minerals and Textile perseverance have used the SLW series water level indicator /sensor.PrincipleA low AC voltage is applied between the probe electrode and the tank wall (or reference electrode in case of insulated tank). When the water/liquid comes in contact with the electrode tip, a conductive path is established between the sense electrode and the tank wall/reference electrode. This current is sensed, amplified and made to operate a relay whose contacts in turn can be used for annunciation/control.Technical infoEvaluation UnitHousing aluminium, Weather-proof enamel painted suitable for back panel/wall mounting.Cable Entries 3 Nos. of BSPMains 110 or 230 Volts AC (-15 to + 10%) 50 Hz.Relay Output 50Hz for non-induc tive load.Power Consumption 5 VA .Fail-Safe Mode High or Low field selectable.Response Time 0.5 secs sack Delay 0.5 to 20 secondsMaximum Sensitivity 25m Siemens operate mode (A) Single point switching.Indication Red LED for Alarm, Green LED for Normal.Operating Temp. -20 C to + 60 C.Weight 2 Kg.
