Van Essen Instruments - Baro-Diver

Micro-Diver

Measuring only 88 mm (3.46″) in length and 18 mm (0.71″) in diameter, the Micro-Diver is Van Essen’s smallest Diver. The Micro-Diver® is a submersible datalogger for long-term, uninterrupted, real-time water level monitoring using a pressure sensor when submerged at a fixed level under the water surface. The pressure sensor measures the equivalent hydrostatic pressure of the water above the sensor diaphragm to calculate the total water depth. The Diver autonomously measures pressure and temperature and records them in its internal memory. The Diver is ideal for ground and surface water level applications. The Micro-Diver is specifically designed for monitoring wells or drive points too small to accommodate larger dataloggers. In addition to its compact size, the Micro-Diver’s memory capacity can store up to 48,000 measurements (date/time, pressure, and temperature) – almost one measurement every ten minutes for an entire year. The Micro-Diver has the following sample methods: fixed length intervals, event-dependent, averaging, and pumping tests. It is available in the following pressure ranges: 10 m, 20 m, 50 m, and 100 m.

CTD-Diver

Waar het nodig is grondwaterstanden en het binnendringen van zout water, geïnjecteerd afvalwater of verontreiniging door chemische lozingen en stortplaatsen te monitoren, is de CTD-Diver® met zijn robuuste, corrosiebestendige keramische (zirkoniumoxide) behuizing met een diameter van 22 mm de ideale oplossing. instrument naar keuze. Het meet autonoom de geleidbaarheid, druk en temperatuur en legt deze vast in het interne geheugen. De CTD-Diver is ideaal voor grond- en oppervlaktewaterpeiltoepassingen. De CTD-Diver is een onderdompelbare datalogger voor langdurige ononderbroken, realtime monitoring van het waterniveau met behulp van een druksensor bij onderdompeling op een vast niveau onder het wateroppervlak. De druksensor meet de equivalente hydrostatische druk van het water boven het sensormembraan om de totale waterdiepte te berekenen. De geleidbaarheidssensor met 4 elektroden meet de werkelijke of specifieke elektrische geleidbaarheid van het water van 0 tot 120 mS/cm. De CTD-Diver kan maximaal 144.000 metingen (datum/tijd, druk, temperatuur en geleidbaarheid) opslaan in zijn werkgeheugen en 144.000 metingen in zijn back-upgeheugen. De CTD-Diver beschikt over de volgende monstermethoden: intervallen met vaste lengte, gebeurtenisafhankelijk, middeling en pomptests. De metingen worden opgeslagen in een vast lengte- of continu geheugen (alleen vaste lengte). De CTD-Diver is verkrijgbaar in de volgende drukbereiken 10 m, 50 m, 100 m en 200 m.

Diver Office

ree, easy-to-use groundwater data management software for Diver dataloggers. Diver-Office is an important part of your water level monitoring workflow and supports all Diver equipment. Set up your monitoring projects and identify your fieldwork tasks; such as a site visit sequence, collection of Diver data, and deployment of Divers. Use Diver-Field to carry out the fieldwork and download Diver data. Once the data collection is complete, use Diver-Office to merge time series, and barometrically compensate the Diver data to convert them into water levels. Visualize data including manual measurements and export data to MON, CSV, or XLSX files for further use in third-party applications. Diver-Office is part of the Diver-Toolkit consisting of Diver-Office and Diver-Field.

Diver Field

Diver-Field: Easy-to-use software to support fieldwork. Streamline your fieldwork workflow and make decision-making in the field easier with Diver-Field. Diver-Field indicates the order to visit the monitoring locations and helps you carry out predefined tasks on-site including downloading Diver datalogger data, collecting manual water level data, and restarting the Diver. Diver-Field also assists you in making decisions in case of water level and clock deviations, such as synchronizing the Diver clock with the computer clock to eliminate time differences. It helps you eliminate data entry errors by real-time data validation, for example, the infamous 1-meter or 1-foot error in manual water level measurements. Moreover, digital data entry eliminates transcription errors due to bad handwriting or damaged notebooks. Diver-Field is part of the Diver-Office included in the Diver-Toolkit installation package. It is an easy-to-use software package developed to read Diver groundwater dataloggers, download Diver monitoring data, and process and display Diver data. It provides strong support for use in the field.

Diver App

Diver-App for Diver-Mate and Diver dataloggers Diver-App allows you to wirelessly connect to Van Essen Instruments Diver dataloggers from your phone or tablet via Bluetooth and the Diver-Mate. Diver-App is available at no cost at the Google Play Store. With Diver-App, you will be able to: Read Diver settings Start and stop your Diver datalogger Validate real-time Diver and manual measurement data Validate the Diver time and project time Download data from your Diver-Mate and Diver datalogger Display downloaded data in a graph Share your data via other apps, for example, WhatsApp or e-mail Transfer your data automatically to the Diver-HUB web portal (or your own FTP server) Start/stop and other features can be switched off to prevent unwanted changes.

Diver-Mate

The Diver-Mate is a field device for simple and fast download of Diver data. Straightforward Data Collection with the New Diver-Mate The Diver-Mate is designed for simple and fast downloading of the data from Diver groundwater data loggers. It increases download efficiency while reducing data transfer errors and connects directly to the DXT-Cable on which the Diver is deployed in a well. The Diver-Mate stores the data in its internal memory, and it can store data from thousands of Divers. A full battery supports up to 5 days of operational use and a LED indicator shows the battery capacity. The Diver-Mate becomes a powerful data transfer tool in combination with the Diver-App for Android. The Diver-App allows you to transfer data from the Diver to the Diver-HUB. Alternatively, the data on the Diver-Mate can easily be transferred to Diver-Office using the supplied USB cable.

Diver-HUB

Diver-HUB is a cloud-based web portal delivering centralized and secure access to your groundwater monitoring data. Diver-HUB is an easy-to-use, cloud-based web portal delivering centralized and secure access to your groundwater monitoring data from anywhere in the world – allowing you to manage groundwater monitoring data in real-time on your desktop, smart phone or tablet. Diver-HUB analyzes Diver datalogger time-series, and creates interactive maps and graphs based on your monitoring data, effectively keeping track of all hardware deployed in the field and supporting the overall management of your monitoring network. Diver-HUB supports Van Essen Instruments’ telemetry solution Diver-HUB also supports traditional data collection with Diver dataloggers

Diver Link

Diver USB reading unit

Connect the Reading Unit to a USB port on a computer to program the Diver data logger. The USB Reading Unit connects to a USB port of a PC, laptop and/or tablet. Simply insert the Diver into the base of the USB Reading Unit to connect to it using the free Diver-Office software. Once connected the Diver can be programmed, settings or data read. The conductivity sensor of the CTD-Diver can be calibrated using the USB Reading Unit. The USB Reading Unit can be used in the field or the office and supports all Divers.

DXT-cable

Quick and easy data downloading with a Diver deployed on a data cable. Deploying a Diver on a Diver communication cable saves time on downloading and provides real-time data from your Diver. Connect your laptop equipped with Diver-Office to the DXT-Cable using the USB Interface Cable to program and read data from the Diver. Available in lengths from 1 meter to 300 meters. This DXT-cable can be used for stand-alone applications or to directly connect to the Diver-Link, Diver-MOD, or Diver-SDI. In case of stand-alone use, not connected to any one of these accessories, the Well Top must be used to seal the cable and prevent it from falling into a well with a diameter of 2 inches or less.
