17. D Failure to attach air and fluid lines to the appropriate ports could result in damage to the bladder A Use of an air source and controller not supplied by Geotech could result in pressure buildup and unexpected pressure storage in the pump and airline Therefore operation of the pump is not recommended with equipment other than that provided by Geotech Once tubing and safety cable are in place slowly deploy the pump screen first into the well If depth to water is known a mark can be placed on the tubing to indicate when the pump has reached the desired level To operate as designed the pump should be fully submerged Optimal pump performance is achieved with submergence of greater than 10 feet of water column Less submergence could result in reduced pumping performance depending on type of fluid being pumped and physical condition of the bladder Older worn bladders can develop a shape memory and may not be able to fill completely without sufficient submergence In any case pumping will still be achieved and the sampling event can be completed A thin less rugged bladder could fill more easily in lower submergence applications Geotech has chosen to implement the use of more reliable heavy walled Poly or robust PTFE material to accommodate longer life of the bladder and overall reliability of the pump Designed for pumping groundwater only other fluids at user s risk System Operation continued Once the pump is

Draft Mode in the chapter for more information 8 Meas Selection of measurement type This is allows the user to specify the type of measurement to be performed This will setup the measure screen for any combination of a 2 6 or 8 tenths measurement so that the measurement screen observation locations are predetermined For example If you were going to do a wading measurement and all of the verticals were going to be 6 tenth observations then you would set the value to 6 Every new vertical will default to an observation depth of 6 tenths In addition the 2 FLOOD option allows for measurements during flood conditions During a flood velocity measurements can be taken at the 0 2 depth location across the section and then corrected to the mean velocity using a velocity profile coefficient Please see the section titled Performing Flood Measurements in the Making Discharge Measurements chapter for more information 9 Measure Time S Set how long the AquaCalc counts clicks for each observation Can be set to JBS Instruments 37 AquaCalc Pro Instruction Manual count for O to 250 seconds The default is 40 seconds Warning Do not set the measurement time to zero the AquaCalc will not be able to measure 10 Pet Q Limit Percent of Total Discharge per Sub section Panel Limit In its Percent Q Automated Mode the AquaCalc can recommend the next tag line distance based upon the velocity in th

Given the greater difficulty in properly adjusting the Pygmy meter these points are more particular to the Pygmy meter than the Price AA but can affect both Bad or Poorly Adjusted Cat Whisker contacts The cam and cat whisker contacts must be cleaned daily before or after usage Oil and carbon build up on the whisker and cam lobe increases the resistance in the electrical circuit causing a week signal that the AquaCalc will reject This rejection of signal was built into the AquaCalc to filter out false signals generated by the wading rod and terminal connectors on the sounding cable when submerged in highly conductive water The wading rod and current meter acts as a capacitor and depending upon the conductivity of the water the signal strength can vary greatly The USGS has published standards for maintenance for current meters in OFFICE OF SURFACE WATER TECHNICAL MEMORANDUM NO 99 06 available from the USGS website Pygmy Meter Spin Test An incorrectly adjusted Pygmy meter whisker can lead to the rapid buildup of carbon deposits in the contact chamber degrading the electrical signal JBS has found JBS Instruments 89 AquaCalc Pro Instruction Manual that a spin test of 60 seconds 5 seconds will provide the correct amount of tension between the whisker and the cam lobe to generate a strong enough signal for the AquaCalc Spin test times less than those recommended above will work but over time they increase carbon
