As of Dec 2025 - GPI Flowmec water meters capable of pulse output are out of stock.
The Sap Spy Water meter requires a Sap Spy Universal Node (sold separately)
A SapSpy Node keeps track of the total sap collected in a sugarbush at each electric releaser. The 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.
