dipperLog VENTED

dipperlog-vented-data-loggerGroundwater Data Logger

The dipperLog VENTED is a reliable, cost effective solution for measuring groundwater levels and temperature in wells, boreholes and open bodies of water. The dipperLog VENTED, incorporates a gauged transducer that measures pressure exempt from barometric influences which is ideal to use in both long and short term monitoring.

The vented data logger is NOW removable from the vent cable allowing for easy field replacement and other deployment applications.

vent-cap-adapter-shallow-wetlandThe NEW Vent Cap Adaptor, especially designed for shallow applications, allows for a true collection of water level measurements without performing barometric compensation. By utilizing the Vent Cap Adaptor, a dipperLog VENTED can be deployed in wetlands or overflow ditches without a vent cable. This cap is specifically designed to allow the barometric pressure to be measured accurately when the cap is exposed while sealing the logger from water intrusion when the cap becomes submerged.

All Heron loggers are available in various deployment options:

Direct Read Version – enables you to do real time readings and download your data while the dipperLog is still in the well.

Reel Version – a portable solution, ideal for short term slug and pump testing

Suspended Version – pull the dipperLog out of the well to download

The dedicated, intuitive software makes the dipperLog quick and easy to program and launch. Simply recover your data, save your findings in a tabular display and graph, view both parameters side by side in a split screen.

“It is the Distributor’s and/or User’s responsibility to ensure chemical, temperature, radiative, and shock compatibility with their site(s) before, during and after deployments. Not doing so will void any and all warranties”

Vent Cap Adapter for Shallow Wetland Studies – PN# 5035

Attach the NEW Vent Cap Adapter for deployments (without vented cable) used in shallow wetland studies. Only available in 10m/30ft pressure range.

PC Communication Cable - PN# 5009
Software – PN# 5008

This cable is necessary to establish a connection between the software and the dipperLog. It connects via the USB port in your laptop or other field device, enabling you to program, launch and download data with ease. This cable can be connected either directly to the dipperLog, to the well head or to the face of the reel.

tapNtell Surface Mount Display – PN# 5020

The tapNtell is a surface mount weather resistant display accessory for the dipperLog well head readout version. The conical connector end of the tapNtell is attached to the direct read well head and the surface mount display unit can be attached to the side of the casing, fence or pump house (any solid surface). The tapNtell provides an instant real time reading of water level and temperature with a tap of a finger.

showNtell Hand Held Display – PN# 5018

The showNtell is a portable hand held display unit for the dipperLog well head readout version. The showNtell can be carried from well to well, to give an instant real time reading of water level and temperature by simply plugging into the direct read well head. The showNtell does not download or store the data from the logger.

SDI-12 Interface Cable – PN# 5021

The SDI-12 system enables the dipperLog data to be accessed from remote locations by a central computer base without site visits. The sensors can be interchanged without reprogramming the data recorder with calibration or other information. The power is supplied to the sensors through a third party device that enables telemetric data readings.
Operating Voltage (DC) :: 7.5 – 35 VDC
Supply Current (Stand-by) :: 10µA
Supply Current (Active) :: 1.5mA

Lockable Well Caps – Compression – PN# 5007

The Nylon well cap is watertight and tamperproof hinged locking cap, ideal for deploying the well head readout version of a dipperLog in a well.

Plug – PN# 5006

The Nylon expansion cap is a watertight locking plug, ideal for deploying the suspended version of a dipperLog in a well.
