Turbidity
Turbidity is the scattering of light caused by suspended particles in a liquid. The light is dispersed in all directions and partially absorbed by the particles, depending on their size, surface area, and color. The measurement of this phenomenon is known as nephelometry.
Turbidity Units:
- FNU (Formazin Nephelometric Unit): Defined by ISO 7027 using infrared light (860 ± 60 nm) measured at a 90° angle.
- FAU (Formazin Absorbance Unit): Also defined by ISO 7027, using infrared light (860 ± 60 nm) measured at a 180° angle.
- NTU (Nephelometric Turbidity Unit): Defined by EPA Method 180.1, using visible light (tungsten lamp) measured at a 90° angle.
- FTU (Formazin Turbidity Unit): Used when turbidity is measured without a standardized angle.
Correlation with Total Suspended Solids (TSS)
An empirical correlation can be established through laboratory analysis of collected samples :
Total Suspended Solids (TSS) are expressed as mass per unit volume, typically in mg/L or as a percentage (e.g., 100 g/L may correspond to 2, 3, ... or 1000 particles, depending on particle type and distribution).

Safety systems for oil-water / grease-water separators
Oil/Light liquid separator monitoring
Oil/Light liquid separator monitoringThe NivOil monitoring system is used with oil/light liquid separators. It is used to monitor the level of the accumulating oil/light liquid layer, the maximum accumulation level in case of blockage of the drainage system and, if applicable, the sludge layer settling on the bottom.
Up to a maximum of three monitoring probes can be connected to the sensor power supply unit - type: NivOil CU (BVS 07 ATEX E 090).
The oil probe - type: NivOil OP (BVS 07 ATEX E 091 X) detects the oil/light liquid layer floating on the water.
The high level probe - type: NivOil HP (BVS 07 ATEX E 092 X) detects a blockage of the drainage system.
This alarm can inform that drainage is blocked.
The alternative high level probe - type: NivOil HPS (BVS 09 ATEX E 021 X) detects a blockage of the drainage system. An alarm signal is triggered as soon as the inflowing water has reached a level that is to high.
The sludge level probe - type: NivOil SP (BVS 09 ATEX E 021 X) detects whether a sludge layer has grown on the bottom of the separator. As soon as the sludge level has reached the too high level an alarm signal is triggered.
All probe inputs are self-configuring.
Therefore, one of the three different intrinsically safe probe types can be connected to each of the three intrinsically safe channels of the power supply unit (NivOil CU). The unit detects which intrinsically safe probe type is connected to which channel and activates the corresponding LED on the front panel.
If a channel is not assigned, its LEDs also remain switched off during operation. The unit has a built-in horn. If necessary, it can be deactivated with DIP switch 1.
Applications
Monitoring of oil/light liquid separators.
Features

Air bubbling level transmitter
Open-channel measurement requires highly accurate level measurement, as the relationship between level and flow is exponential. This measurement system combines an air generator with a highly accurate pressure sensor. On the air circuit, a sensor measures the pressure required for the effective release of air bubbles. The pressure measured is then equal to the hydrostatic pressure of the liquid column at the air discharge point.
To minimize measurement error due to air flow variations between high and low levels, the injection pump features a microvalve. The “0” and full scale settings are accessible to the user. The level can then be transmitted as a 4-20 mA signal.
The BAMOBUL level sensor consists of an IP 55 wall-mounted enclosure housing the pressure sensor, power electronics and air generator. Pneumatic connections are provided by instant fittings for Ø 6x4 rilsan tubing between the housing and the injection pipe. Electrical connections are made via a screw terminal block in a weatherproof enclosure. The 316 L stainless steel injection pipe features a sliding adjustment device.
