    Section 1 sample source, the time required for liquid to reach the sensor will increase. The microprocessor automatically compensates for this change by allowing the peristaltic pump to deliver sample liquid for a corresponding longer period of time. Conversely, if suction lift decreases due to an increase in level at the sample source, the time required for liquid to the sensor will decrease.

    In addition to performing basic sampling routines, Sigma 900 All Weather Refrigerated Samplers that are equipped with the storm water monitoring program have the following additional capabilities.

  • Page 45: Programming Instructions For Storm Water Sampling Routine

    Section 5 • When sampling with multiple bottles, the sampler can be programmed to collect one large “first flush” sample (or small multiple samples) at timed interval(s). The number of bottles segregated for the first flush sample is selectable. Concurrently, flow weighted samples are collected from the beginning of the storm until all remaining bottle(s) are filled, or after a user selected time has elapsed.

  • Page 46: Special Outputs

    Section 5 Item Message Description of Message Number There are two sample volume calibration methods, “Auto Calibrate” and “Timed Calibrate”. The Auto Calibrate method uses the liquid sensor to determine sample volume and can only be used if the sampler is located above the sample source. The AUTO CALIBRATE? intake tubing must slope downward from the sampler to the source and should be free of any loops.

  • Page 47: Programming The Sampler For Special Outputs

    Section 5 The valve isolates the sampler intake tubing from the pressurized line between samples and facilitates changing the pump tube. It is necessary to have an external separate power supply/source to operate the valve. Mode 3 (Fault Output) The sampler sends a 12 V dc output for one second in the event of a missed sample.

    Section 5 5.14.5 Timed Bottle—Pre-Advanced Mode When using the timed bottle mode explained above, there may come a case where the bottle fills up before the desired time for the bottle is complete. Normally, if this occurs and a new sample is requested, the sample is missed because the bottle is full and it is not time to move to the next bottle.
  • Page 51 Section 5 2. Multiply the flow increment between samples, f, by the pulse frequency output of the flow meter (i.e. 1 pulse per 100 gallons, 1 pulse per 1,000 gallons, etc.). If the pulse frequency output of the flow meter is not known, consult the flow meter manufacturer.
  • Page 52 Section 5 Flow Proportional Sampling, External—Using 4–20 mA Signal Converted to Pulses, Flow Signal Interface The Flow Signal Interface (Cat. No. 2021) is an optional 4–20 mA interface that converts 4–20 mA current signals (from a flow meter) to 12 V dc pulses. At 20 mA, the interface transmits ten 12-volt pulses per minute.
