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.

Totalizers for Natural, Propane, and Butane Gas

Often used in heating, cooking, and power-generating systems, these totalizers measure the total amount of natural gas, propane, and butane that flow through them. They use positive displacement, so they measure the flow by passing specific volumes of gas through their diaphragm. Their total cannot be reset. Mount them inline with your pipe system.

Totalizers for Fuel

Determine the amount of gasoline, diesel fuel, and kerosene that flows through these totalizers. They measure the total amount of flow and can be set to measure in batches, which means they measure up to a certain volume. The total cannot be reset, but the batch measurement can. They use positive displacement, so they measure flow by passing specific volumes of liquid through their chamber. They’re accurate in any mounting orientation. Mount them inline with your pipe system. Their mesh strainer traps debris to help prevent clogging.
These totalizers are calibrated with diesel fuel. You can recalibrate them in the field to other liquids, pipe, and operating conditions.

Totalizers for Oil

Measure the amount of light oil that flows through these totalizers. They use positive displacement, so they measure flow by passing specific volumes of liquid through a chamber. Their total can be reset. Manually or automatically turn them on, and they automatically shut down 40 seconds after flow stops. Their mounting orientation won’t affect their ability to measure flow correctly. Install these totalizers directly inline with your pipe system using the fittings on each end. The fittings are 316 stainless steel, so they resist impact better than plastic fittings. Products cannot be sold outside North America due to restrictions.
These totalizers are calibrated with water. You can recalibrate them in the field to other liquids, pipe, and operating conditions.

Ultra-Low-Flow Flow Transmitters
Often used in low-flow metering applications for lubricants or antifreeze, these transmitters measure flow rate and send the data to a remote display or programmable logic controller (PLC). To measure flow, they have oval-shaped gears that move the liquid through the flowmeter—how fast the gears turn correspond to the flow rate. Also known as transducers, they help you monitor status or control equipment by converting measurements to an electrical pulse that can be interpreted by receiving devices. The higher the flow, the more pulses they send. Mount them inline with your pipe system. They’re accurate in any mounting orientation.
These transmitters are calibrated with oil but can be used with other liquids and will generally measure accurately, even if they differ in viscosity and density.
