Oil, petrol and other hydrocarbons pose a great danger to ground and waste water pollution.
Afriso Eurogauge offer a full range of alarms both mains and solar powered to monitor buildup in oil/petrol separators and grease traps.
The OSA monitors the level of the separated liquid in oil/petrol separators and generates an alarm signal when it is necessary to empty the separator.
In addition, the maximum permissible level in the separator can be detected, preventing overfilling.
OSA consists of an alarm unit, an ES4 capacitance sensor for detecting the layer level and an optional WGA-R6 PTC thermistor sensor for detecting the maximum permissible level or ES8 silt sensor. The alarm unit has 2 relay outputs, audio/visual alarms and also test and re-set buttons. The alarm unit monitors the sensors for short circuits or cable breaks in the sensor circuits.
The ES4 probe is mounted at least 150mm below the normal level of the separator. When the oil or petrol layer reaches the critical level, the unit generates an alarm signal. By installing the WGA-R6 probe above the normal level, the maximum level in the separator can also be detected. If the ES8 sensor is fitted then silt levels in the separator can be monitored.
The WGA 02 monitors the thickness of the layer of separated liquid in oil, petrol and grease separators and generates an alarm signal when it is necessary to empty the separator. The WGA 03 can also detect the maximum level in the separator. This prevents overfilling caused by clogged outlets or other circumstances.
WGA 02 consists of an alarm unit and a WGA-SD conductivity sensor for detecting the separating layer level. The alarm unit has 2 relay outputs, audio/visual alarms and also test and reset buttons. The WGA-SD sensor is mounted below the normal level of the separator. When the oil, petrol or grease layer reaches the critical level, the unit generates an alarm signal.
WGA 03 has an additional WGA-AS capacitance sensor mounted at the maximum permissible level. An alarm is triggered when the maximum level is reached. The alarm unit monitors the sensors for short circuits or cable breaks in the sensor circuits.
When used with the WGA-OW floating probe, the WGA 06 detects buildup of oil in separator sumps or shafts and generates an alarm before pollutants are discharged into the main drainage system. It is also possible to use the WGA-AS sensor which enables the detection of maximum levels in separators or retention tanks.
The WGA 06 consists of an alarm unit and a capacitance sensor. The alarm unit has 2 relay outputs, audio/visual alarms and also test and re-set buttons. The alarm unit monitors the sensors and signals short circuits or cable breaks in the sensor circuits.
The WGA-OW floating sensor or WGA-AS fixed sensor can be connected. The WGA-OW floats on the surface of the water in the shaft and generates an alarm signal when an oil, grease or petrol layer of at least 15 mm thickness has built up. The WGA-AS is mounted above the normal level of the separator or the retention tank. An alarm is triggered when the maximum permissible level is reached.
The SOL 3000 STD has been designed to monitor hydrocarbon levels in oil separators and interceptors in locations where mains power is unavailable.
The system comprises of an IP65 rated enclosure containing an ATEX approved oil separator alarm, solar panel, battery and monitoring electronics mounted on an angled galvanised steel pole and flange assembly with an integral 10m sensor cable which may be extended to a maximum of 300m. An optional wall mounting bracket is also available.
A specially designed fail-safe solid state sensor is mounted at the required level in the separator chamber. A high intensity flashing beacon on the top of the enclosure warns that the separator requires emptying, or of sensor fault (short/open circuit) conditions.
An integral solar panel trickle-charges the heavy duty lead acid 18AH battery.
A Test/Reset button is provided to check operation by simulating an alarm condition. To conserve battery power, the SOL 3000 is active for 20 seconds every 60 minutes.
If an alarm condition is present, the high intensity beacon will flash until the alarm condition is cleared. There is sufficient battery capacity for the beacon to operate for 7 days in poor light conditions.
On cleaning the separator, the SOL 3000 is reset by pressing the Test/Reset button.
The SOL 3000 SLA has an optional additional ES8 silt/sludge detection sensor which works in conjunction with the ES4 oil/water sensor. On pressing the Test/Reset button, LED indicator lamps on the side of the enclosure show which alarm has been triggered. The beacon operates for both alarms. To conserve battery power, the SOL 3000 is active for 2 minutes every 60 minutes.
The SOL 3000 GSM has an internal GSM unit and antenna fitted in place of the beacon. The GSM unit can use either pay as you go or contract SIM cards from any mobile operator. SMS text messages are sent to nominated mobile phones when an alarm condition occurs.
The SOL 3000 GSM is available with either the oil sensor or oil and silt sensors.
