FAQ

dipperLog NANO groundwater data logger

Q:Is the dipperLog NANO’s battery field replaceable?
A:No, the dipperLog NANO will have to come back to Heron Instruments for service.
 
Q:Can the dipperLog NANO be deployed in areas that are subject to freezing?
A:The dipperLog NANO will operate at temperatures below freezing, however if ice forms on the pressure sensor, damage could occur.
 
Q:What is the difference between vented and non-vented groundwater data loggers?
A:The vented logger automatically compensates for barometric pressure changes, a non-vented logger does not.
 
Q:Why do I need the barLog NANO along with the dipperLog NANO?
A:A barometric logger is used to automatically compensate readings stored on the dipperLog NANO for changes in barometric pressure (for non-vented version). The barLog NANO is recommended for long term monitoring or where more than one logger is deployed within a 20 km radius.
 
Q:How do I setup the barLog NANO to work with the dipperLog NANO?
A:The barLog NANO must use the same job number as the dipperLog NANO on the jobsite (within 20km radius). The barLog NANO should be set up and started before the dipperLog NANO and downloaded after the dipperLog NANO (insuring that all dipperLog NANO data has been retrieved from multiple wells).
 
Q:Will the dipperLog NANO be damaged if it’s submerged under more water than its maximum rating?
A:The dipperLog NANO can withstand 2 times its rated pressure before damage will occur.
 
Q:What pressure range do I need?
A:Pressure range refers to the maximum height of water above the transducer. Read our Tip Sheet for more details.
A - Barometric
B – 0-30FT/10M
C – 0-100FT/30M
D – 0-200FT/60M
E – 0-400FT/120M
 
 

H.OIL and Sm.OIL oil/water Interface Meters

Q:What does the Interface Meter detect?
A:The interface meter will detect both floating (LNAPL) and sinking (DNAPL) non-conductive product with a solid signal and water (conductive) with an intermittent signal.
 
Q:Why doesn’t the Interface Meter work when testing out of the well?
A:The probe is being washed out by ambient infrared light from the sun or incandescent light. Shield the probe from light while testing.
 
Q:How do I know if the battery needs replacing?
A:When the green “on” light flashes in unison with the red LED light.
 
Q:The Interface Meter continually sounds/beeps when not in water?
A:If you have taken the electronic panel off the unit and reinstalled it upside down the unit will continually sound. Make sure the battery box is situated directly under the Heron Instruments logo
 
Q:Why does the Interface Meter have a “grounding lead”?
A:The H.OIL and Sm.OIL Interface Meters are CSA certified intrinsically safe. The ground lead should be attached to a suitable grounding source during use – example: steel casing, metal wellhead cap, metal rod driven into the ground, etc. Check your local grounding regulations when working in hazardous conditions.
 
Q:What do I use to clean the probe tip?
A:We suggest a diluted dishwashing detergent and a soft brush.
 
Q:I changed the battery and cleaned the probe but the interface meter still does not work.
A:Make sure the two thumb screws securing the electronic panel to the unit are tight. They cause the contact from the back of the electronic panel down the tape to the probe. Make sure the battery is installed correctly.
 
Q:I need to have the instrument serviced.
A:Contact your supplier or complete the RMA Request Form.
 
Q:Is there a video I can watch for more info?
A:Yes, we have product videos available on our individual product pages, and our YouTube account.

Water Level Meters – dipper-T, Water Tape, Little Dipper

Q:Why doesn’t the water level meter sound when the probe is in water?
A:Do not test the instrument in distilled or deionized water. Make sure the two thumb screws holding the electronic panel to the unit are tight. They cause the contact from the back of the electronic panel down the tape to the probe. Turn the sensitivity control to maximum sensitivity (fully clockwise). Change battery.
 
Q:Why does the unit work when tested in tap water but not in well water?
A:It may be that the well water is extremely pure. The lowest level of purity (conductivity) that the unit will work in is 13 µS+/_5%.

If you are measuring water at these conductivity levels, contact Heron Instruments and ask about our high sensitivity dipper-T panel.
 
Q:Where is the ON/OFF switch?
A:There is no switch. The water acts as a switch, the knob in the center of the panel adjusts the sensitivity of the unit to give clear and unambiguous signals. The unit does not consume any power when it is not in water except in drawdown mode.
 
Q:Why is the dipper-T always sounding/beeping out of water?
A:If the dipper-T has a serial number that ends with a “–T”, the unit may be in drawDown mode. Drawdown mode is indicated by a yellow LED. Push the mode change button to put your water level meter back into static mode.
 
Q:Can the probe sound (measure) to the bottom of the well?
A:Yes, the probe is fully pressure rated to the length of the tape (3/8” probe to 300’ for 20 minutes).
 
Q:What do I use to clean the tape, reel and probe?
A:Before cleaning the unit we suggest removing the electronic panel. Clean the unit with diluted dishwashing detergent. For biological decontamination use a mildly diluted bleach solution followed by a wash down from a hose, distilled or deionized water or follow locally mandated procedures.
 
Q:I need to have the instrument serviced.
A:Contact your supplier or complete the Heron RMA form.
 
Q:Is there a video I can watch for more info?
A:Yes, we have product videos available on our individual product pages, and our YouTube account.

Q:How do I install a 5/8" Water Level Meter Probe?
A:Watch our video to learn how to install a 5/8" Water Level Meter Probe.
 
Q:How do I install dipper-T drawDown Probe and Link?
A:Watch our video to learn how to install a dipper-T drawDown Probe and Link.
