Application Notes

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

Inexpensive Batch Control

The Background: The customer, a water treatment company focusing on corrosion control, is developing new procedures and requires a flow meter to be used as part of their testing protocol.

The Problem: The flow meter must be compatible with a batch controller and price is a major consideration.

The Solution: We recommended the GPI TM series with pulse output paired with the KEP MB2 batch controller. These were used to control a Georg Fisher Type 104 ball valve. This set-up allows precise batching at a great price.
