Work is our favorite four letter word. It’s also what defines us as
a customer-centered sensor company.


No. Kodiak Instruments’ liquid level monitors are battery-powered and last 5-10 yrs in any location. The Gateway transceiver is also powered by a battery, but is charged daily via solar panel.

15 minutes. Our sensors have no wires and are transmitting when they arrive to a wellsite. We recommend having two people to insert the sensor through the 3” or 4” threaded portal on the tank top. It should only take about 10 minutes to install one liquid level monitor.

We recommend that you loosen the threaded 3” or 4” port plugs on the top of the tank prior to installing the sensor. Many of these plugs can be difficult to unscrew after years of non-use.


We recommend that you mount the gateway box on either a pole or a wall of a structure on the well site. You must supply your own mounting bracket. If the well site is off-grid and has no power, we provide a solar panel that charges the gateway box. You must install the panel in a place that collects sun throughout the day and does so at a 30 degrees on a downward angle, facing south.

Kodiak Instruments’ web portal is run completely from the web, no software is required. Access to the online application can be reached using any platform or browser.

Kodiak Instruments’ sensors collect data and transmit it wirelessly to the Kodiak gateway transmitter. The gateway sends small packets of data through a private and secure cell/satellite network. The data is received by layers of private and protected cloud servers where the data is analyzed and delivered to your web portal dashboard.

Kodiak sensors and gateways are pre-configured to recognize each other (M2M programming) as soon as the sensor is within transmission range – or once it arrives to the well site.

The standard Kodiak Gateway control box can support up to 50 tanks. However, to maintain continuous up-time, we recommend one gateway per well site.

Yes, there is a monthly flat fee for the data service per well site. However, we offer a 20% discount on transmission costs if the data is purchased up-front. Customer data credits are generally purchased in 24 month packages at the discounted rate.

The Kodiak Instruments’ 2 year warranty covers all equipment except for vandalism, negligence, an act of God, or theft.

Yes, Kodiak can provide flexible solutions that can work on underground and above ground tanks.

Our intent is that our product is simple enough for our customers to install by themselves. However, Kodiak can provide installation at an additional cost.

Yes, the NEMA enclosures that are external to the tank are guaranteed for nearly any natural environment. They will withstand temperatures from -40 to 140 degrees Fahrenheit. The portion of the sensor that is internal to the tank is rated from -15 to 185 degrees Fahrenheit.

Kodiak’s implementation of IoT technology allows small packets of sensor data to be transmitted using minimal cell services (much less than is needed to send or receive a phone call). Kodiak has both cellular modem and satellite technology that allows you to install a sensor in any tank, anywhere.

Kodiak Instruments’ sensors have a rated resolution of at least .25″.

The Liquid Level Monitors can measure two fluids in the same tank. The sensors can be configured to measure any liquid, but generally interfaces with a petroleum product on top (sweet, sour, paraffin, condensate oils) and water on the bottom.

No, there is no limit to the size of the tanks that are supported with our tank monitoring equipment.

Kodiak sensors are pre-calibrated when they leave our facility and should last the lifetime of the sensor. However, you have the ability to re-calibrate as needed on our mobile web interface.

Yes. The difference between Div 1 and Div 2 is all about the constancy of the threat of explosion. If the threat is constant, or common, it’s classified as Div 1. If it’s possible, but not common, it’s Div 2. Therefore, a Div 1 rated sensor is safe in all Div 2 areas.

Explosion proof is a method of containing sparks within a small housing, and allowing the expanding gasses escape into the atmosphere only once they are cooled. This keeps the spark from turning into a fire or explosion. The wiring to support this method is quite involved and expensive as everything has to go through sealed conduit. This protection method is necessary for high powered devices such as pumps.

Intrinsic safety prevents sparks, fires, and explosions by never allowing enough current in the electronics to cause a spark or generate heat. The sensors are designed to operate on this low current, and an electrical barrier is placed between the sensor and the power source to control the current and eliminate surges and spikes. This protection method is safer and typically less expensive to wire.

Divisions and Zones are the result of two methods to express similar ideas. They each describe the constancy of the hazardous mixture in a hazardous area.

Divisions are used in the US, and divide hazards into two categories:

Div 1 is an area where the threat of fire or explosion is possible under normal operating circumstances. This includes normal maintenance and repair operations. Div 2 is an area where the threat is only possible under abnormal circumstances, like equipment failure.

Zones are used in Canada, Europe, and many other places. This method divides hazards into three categories:

Zone 0 describes a constant threat under normal circumstances. Zone 1 describes an intermittent threat under normal circumstances. Zone 2 is an area where the threat is only possible under abnormal circumstances.
