The GF Signet 8150 Battery Operated Flow Totalizer is compatible with the GF Signet 515, 525, and 2517 flow sensors, and will provide years of dependable operation. The large digital display indicates flow rate and totalized flow volume simultaneously.

The GF Signet 8150 flow totalizer has three totalizers. One of the three totalizers is resettable from the front panel or a remote location, while the second resettable totalizer can only be reset by entering a user selectable security code. Meanwhile, the third is a permanent non-resettable totalizer. The Signet 8150's intuitive software design and four-button keypad provide for simple operation while setting screen displays and programming the system.

Calibrating the GF Signet 8150 flow totalizater is easy - just go into the Auto-Cal feature and enter a value to match an external reference. Screen displays can be modified to suit the user's needs; along with the flow rate, any of the three totalizers can be selected as the displayed totalizer. Customers can quickly scroll through the totalizers simply by pressing any key on the keypad. A display averaging feature is included for applications where the flow in the pipe fluctuates. For applications where flow stops and starts due to production needs, a no-flow indicator will display the hours of non-flow.

The GF Signet 8150 is available in either panel or field mount configurations. Additionally, the 8150 is available with the GF Signet 515 paddlewheel sensor integrated into a single unit.

Application Notes

Here's how some of our customers used this product.

Remote Water Usage Monitoring

The Background: The customer operates a mine that provides aggregate to the concrete industry and requires a flow meter to monitor water usage at their facilities.

The Problem: The mine is in a very remote location and no power is available at the desired metering points.

The Solution: The battery powered GF Signet 8150 flow totalizer with integral paddle wheel flow sensor provides an economical solution for recording total water usage. The long (~4yr) battery life allows the customer to visit each metering point, and reliably record usage without the expense of running power to each location.
