| The ML-54 MLSS Metes is a portable sludge concentration meter thar performs measurements of transmitted light to make simple on-site measurements of the concentration of activated sludge in sewage,wastempurification tanks and plant wasteater treatment systems and of sludge zone in nitrification and sedimentation tanks Features 1.Sludge concentration and water depth can be measured simultaneously 2.Automatic zero calibration functionality 3.Extensive calculation functionality JIS conversion (The JIS method referred to here is that of manual analysis by weight) Internal Y=aX+b calculation. Sludge concentration in an aeration tank with large fluctuations in concentration can be read directly from the manual analysis(weight method)correlation correction JIS conversion values can be read directly by performing measurements on multiple sludge samples of different concentrations with both manual analysis(weight method,Y value)and the MLSS Meter (ML-54,X value),finding the values of coefficients a and b,and using these values as inputs Sludge volume index(SVI)and sludge return rate (r)calculanion Input SV(sludge sedimentation rate)to find SVI(sludge volume index)and r(sludge return rate). 4.Sludge zone level detection(alarm on detection)Input the sludge zone concentration as a transmissivity percentage to obtain an alarm on reaching the sludge interface 5.Low-battery-voltage warning display 6.Automatic shutdown functionality for neglect to turn power off power turns off automatically ten minutes after end of use (time to shutdown may be set by user) 7.Connect to printer(optional)to print measurement readings Principle of Measurement The ML-54 MLSS Meter employs light absorption as its principle of measurement This measurement method is grounded in the principle that "the absorbance of light in a solution is proportional to its concentration when the optical path length is uniform". Light given off by the light-emitting unit is absorbed and attenuated by MLSS(suspended solids in activated sludge)at the sensor placed in a measurement tank (anaeration tank )The ML-54 MLSS Meter finds MLSS concentration from the light absorption (the amount of light absorbed by material,expressed as a logarithm of the reciprocal of transmission )with little interference from the color of the sample and provides a digitalreadout Water depth is found from the signal from the pressure sensor of the sensor placed in a measurement tank and provided in adigital readout SZ(Sludge Zone)may also be measured by setting the parameters Specifications Measurement method：Transmitted light Measurement range： Sludge density 0-15000 mg/L Water depth 0-20 m (10 m standard cable) Sludge zone : 10000mg/L or more SZ alarm (0.0-99.9% transmissivity) Reproducibility： Sludge density Readout ±3% Water depth ±0.1m Readouts： Concentration：LCD, 5 digits, 1 mg/L minimum Water depth：LCD, 3 digits, 0.1 m minimum Light source：LED Sensor：Silicon photocell Calculations： 1)JIS conversion Y=aX+b 2)Sludge volume index SVI=SV%/MLSS% 3)Sludge return rate r=SVI x MLSS%/[100-(SVI x MLSS%)] 4)Span X=A x C/B 5)Auto-zero Specimen memory：1-99 specimens Error messages： 1)Zero alignment failure 2)Print failure 3)Low battery voltage 4)EEPROM error Power source： Nickel-hydrogen batteries (4 cells) Automatic shutdown functionality Uptime：20 hours continuous use Dimensions： Main unit 210 (W) x 85 (D) x 78 (H) mm Sensor：59 (diameter) x 153 (length) mm, 10-meter cable Weight：Main unit 1.5 kg Sensor 2.5 kg External output：RS232C, one port (Option)：Transmission rate: 9600 bps Options : Printy3 (ML-54 printer) ISO 9001 Certified 历史资料:2007-04-09版本 | 污泥浊度计/便携式MISS测量仪C1/JP-ML-54 |
