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.

These indicators come with a calibration certificate traceable to NIST that states they've passed a test for accuracy. All are calibrated at 72° F. In addition to measuring the strength of a magnetic field in gauss, they also measure the direction of a magnetic field in positive/negative. To take a measurement, place the lower edge of the indicator near or against your tools and parts.

High-Accuracy Flow and Temperature Transmitters
![](/prerenderstable/mvPRE/contents/gfx/imagecache/439/4397n101_41d051be-97bb-4a6c-b7c5-e8b0f517fd6f@halfx_1697030920.png?ver=imagenotfound)
Also known as magmeters, these transmitters use a magnetic field to measure flow rate and temperature with high accuracy. Because they use a magnetic field, they only work with conductive liquids, such as water. These transmitters, also known as transducers, convert measurements to an electrical signal that can be interpreted by receiving devices, such as remote displays and programmable logic controllers (PLCs) to monitor flow or control equipment. For your receiving device to interpret the signal, you will need to calibrate it for the measurement range and output signal of the transmitter. As flow or temperature increases, the output signal increases. These transmitters have one analog output for flow and another for temperature. They only give accurate readings within the rated measurement range. A digital display makes it easy to view readings and adjust settings at the source. Mount these transmitters inline with your pipe system. They measure flow correctly in any mounting orientation.
These transmitters are calibrated with water. They can only be used with liquids with a conductivity of at least 20 µS/cm.

Motion-Measuring Modules for Development Boards
![](/prerenderstable/mvPRE/contents/gfx/imagecache/818/8184n12-f@halfx_me5gr_1718024020.png?ver=imagenotfound)
Measure your device's acceleration, rotation, or orientation. These modules gather data over time and track movement, which can help improve performance, debug issues, and calibrate your components. Solder them onto a development board. To connect them to your device, solder on a wire or header. For a solderless connection, use a Qwiic cord (not included).
An accelerometer measures the rate at which your device is speeding up or slowing down. A gyroscope measures how fast your device is rotating. A magnetometer measures your device's orientation.
