About Flowmeters and Totalizers
Flowmeters measure the rate of flow for a liquid or a gas. Totalizers measure the cumulative flow volume. Flowmeter/totalizers display both the flow rate and the cumulative flow volume.

High-Accuracy Totalizers for Fuel

More than twice as accurate as standard totalizers for fuel, these measure the total flow volume of gasoline, diesel fuel, and kerosene with ±2% accuracy. They display a resettable batch total volume to keep track of one metering application and a nonresettable total flow volume. The mesh strainer traps debris.

Flowmeter/Totalizers for Oil and Fuel
Use these flowmeter/totalizers to measure both the flow rate and total flow volume of oil, gasoline, diesel fuel, and kerosene. They display a batch total volume that can be reset after each metering application and a total flow volume that cannot be reset. All flowmeter/totalizers are FM approved for Class I, Divisions 1 and 2, Groups A, B, C, and D; Class II, Divisions 1 and 2, Groups E, F, and G; and Class III, Divisions 1 and 2 hazardous locations. They have an enclosure that meets NEMA 4 for protection from dirt and washdowns.
Certificate of calibration traceable to NIST states that the flowmeter/totalizer has passed a test for accuracy.
Optional remote panel-mounting kit lets you mount the meter’s display up to 100 feet away. It includes a sensor module and 10 feet of cable with wire leads.
Hazardous location environmental ratings indicate where manufacturers have included safety features in products to facilitate their safe use in hazardous environments. Before selecting a product for a hazardous location, ensure it is rated for your environment. See About Hazardous Location Environmental Ratings.

Clear Scratch- and UV-Resistant Acrylic Tubes
- Color: Clear
- Temperature Range: -40° to 180° F
- Tensile Strength; 9,195-11,030 (Good)
- Impact Strength: 0.040 ft.-lbs./in.
- Hardness: Rockwell M89-M96 (Hard)
- For Use Outdoors: Yes
