- Attractive design with bodies that are cut and precisely machined from transparent, solid acrylic blocks permits full visual examination.
- Improved reading accuracy because to the float's distinct appearance against a smooth white background.
- With direct reading scales that are hot stamped into the plastic, there is no need for difficult conversions, and the product's operational life is extended.
- High repeatability due to tapered bores that are precisely machined.
- Reasonably priced installation with choices for back or end connections and metal mounting inserts that may be directly supported by system pipes.
