A SapSpy Metering Node keeps track of the total sap collected in a sugarbush at each electric releaser. The metering node tracks the total gallons or liters pumped at every 5 minute interval. Within the Sap Spy web app, we then calculate and visualize the following:
Total gallons for the season
Total gallons/tap for the season
Gallons/reading
Gallons/Hour
Gallons/Day
Gallons/Tap/Day
This data helps you track your total production for the season helping you optimize your operation. Data is maintained year over year for ongoing seasonal comparisons.
The following meters have been tested and work well with a Sap Spy metering node (sold separately). The prices listed here are competitive with purchasing direct from EKM or GPI directly as well as from other resellers. Purchasing from Sap Spy includes electrical connectors making it easy to connect to directly to the Sap Spy metering node.
If you already have a GPI flowmeter and would like to add the pulse counting functionality to it without swapping out the entire meter. Please reach out as that can be sold separately at a significant discount over purchasing directly from GPI.
Sensor nodes are in stock for the 2025 season. Most orders ship in 1-3 days.
A SapSpy Sensor Node communicates to the SapSpy Sensor Hub (Sold Separately) allowing you to measure vacuum at different locations in your sugarbush.
A sensor node can be one of the following configurations:
1) Single Vacuum Sensor with temperature sensor
2) Dual vacuum sensor with temperature sensor
3) Single Vacuum Sensor with Ultrasonic Tank level sensor and temperature sensor (used for a tank and releaser)
4) Single Ultrasonic tank level sensor and temperature sensor (Typically used where an electric releaser pumps to a remote tank where vacuum monitoring is not needed).
In order for SapSpy Sensor Nodes to communicated to the SapSpy Sensor Hub, the Sensor Hub must include an add-on radio option for +$100.
Sap Spy nodes are now capable of Spy Mesh. Spy Mesh allows nodes to repeat a signal in order to significantly increase the distance between end of line vacuum sensors and the sensor hub (Cellular Gateway). Videos and additional instructional content will be updated in Q4 of 2022 discussing this new and exciting functionality.
A single sensor hub can service many sensor nodes (currently up to 40). The recommended maximum number of hops between a sensor hub and sensor node is 4. The expected distance between two sensors nodes is estimated at ~1500' - 2500' through a typical sugarbush. Line of sight, sensor nodes can reach 3 miles+ between two nodes. It is recommended to use a dedicated Sensor Hub per sugarbush location and use that particular Sensor Hub to service all sensor nodes in the local sugarbush.

Metering nodes will be a limited release for the 2025 season. Customers who purchase a limited release version will have an opportunity for a free upgrade if hardware changes are required.
A Sap Spy metering node is simply a pulse counter. It is universal and operates with any water meter that produces a pulse output. If you already have a water meter with pulse output capability, there is no need to replace it. Simply use this node directly.
If you don't already have a metering node, one can be purchased separately.
Pulse counting can also be used to count the total number of dump cycles from a mechanical releaser allowing you to track total volume of sap processed and average time taken between dump cycles. This requires a magnetic reed switch also sold separately.
