Vulink is a global cellular telemetry device that will change the way you think about remote monitoring. The device is easy to set up, works from anywhere and delivers long-lasting power. So, you never have to worry about your equipment or your data.

VuLink is part of the most complete monitoring solution available. Instrumentation, telemetry and software work together within In-Situ's shared ecosystem to make it easier than ever to collect, access and manage your data.


One-Press Setup

VuLink autodetects any In-Situ device with one button press or scheduled report. Icons indicate battery life, instrument connection, network connection and HydroVu connection.

In-Well Mounting

The cost to install a pole for device mounting is typically more than the cost of an entire In-Situ telemetry and level monitoring system. Save time and money by installing the VuLink inside a 2-inch/50 mm well with standard well caps and casings to keep it secure and hidden from view.

Free Global Cellular Data

VuLink CI offers free data for life, right out of the box, no set up required. Forget about provisioning SIM cards and checking multiple systems for data usage; VuLink and HydroVu promise free transmissions of a limited number of parameters and readings once per day. Upgrade for a small monthly fee to increase parameters and readings.

Extended Life

VuLink CI provides two-to-five times the battery life of similar devices. M1/NB-IoT offer extraordinary power savings. And at faster reporting rates, VuLink offers exponential are supported.

Enhanced In-Device Alarms

VuLink supports having a different reading and report schedule when in an alarm state. This enables VuLink to conserve battery and bandwidth when everything is normal and get the real-time response for critical events.

Continuous GPS

HydroVu uses VuLink’s GPS to automatically locate and mark devices on maps, synching devices and locations, increasing data quality, and making it easier to track free-floating buoys.

Complete Monitoring Solution

In-Situ’s complete monitoring solution, with HydroVu, In-Situ telemetry, and In-Situ instrumentation, works better than any pieced-together solution. In-Situ performs comprehensive, end-to-end integration testing. And if a problem occurs, our Tech Support team will be available to support the whole system.

Enhanced Reliability

VuLink is completely sealed and designed to go in the water. A new innovative design for venting allows desiccant-free operation with non-vented and vented instrumentation. Ryton construction holds up to 280 lbs. And firmware can be updated over the air.

VuSitu Mobile App

Use VuSitu to perform advanced setup on your iOS or Android device. Bluetooth Low Energy (BLE) communications support connection without pairing or cables. And Beacon Mode BLE communications lets you connect to VuLink and connected instruments without physical access.

Barometric Compensation

Automated barometric compensation removes the effects of atmospheric pressure changes to improve system accuracy. Save time and potential for error vs. manual correction.


Surface Water

Monitor inland or coastal water easily and accurately with equipment designed to work together.

Continuous Groundwater Monitoring

Measure water level and water quality over time at local or regional scales.

HAB Monitoring

Remotely monitor for harmful algal blooms for quick response and improved trend analysis.


Manage water entering, moving through and leaving a mine site.
