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.

Tablet Holders with Emergency Stop Push-Button Switch
Halt machinery in an instant with these tablet holders. They equip your tablet with safety switches that meet IEC and EN standards, so you can safely move around your equipment while teaching robots or monitoring production lines and conveyor systems.
The emergency stop switch on the front of the holder illuminates when the switch is enabled. There is also a deadman switch on the back of the holder that controls machinery when you lightly press and hold it in the middle position. If the switch is released or pressed down all the way, it stops the machine.
Pivot the handle to hold a tablet vertically or horizontally, while keeping the switches in a comfortable position for either hand. The adjustable mounting bracket secures a variety of tablet sizes. Connect your tablet to the USB port to charge during use.
Bracket adjustment kits enlarge the bracket to hold tablets with thick covers and protectors.

Differential Pressure Switches for Air
Often used with ovens, dryers, and HVAC systems, these switches detect small differences in air pressure to indicate a filter is clogged or help you maintain a certain air pressure. When the differential pressure reaches your setpoint, these switches can turn equipment on and off, activate automated controls, or signal alarms. They are single pole, double throw (SPDT) and can be installed to turn one circuit from off to on (normally open) or from on to off (normally closed). All meet at least one safety standard.
When measuring pressure in ductwork, pair them with a static pressure probe.
NEMA 13 rated switches can be used in dirty, damp, and oily areas. Switches rated IP54 protect against dust and splashing water.

Hazardous Location Differential Pressure Switches for Air
With an explosionproof enclosure that meets NEMA 7 and 9 standards for hazardous locations, these switches were tested and verified by UL and CSA for use where explosive gas or dust may be present. Often used with ovens, dryers, and HVAC systems, they can indicate a filter is clogged or help maintain a certain air pressure. These switches turn equipment on and off, activate automated controls, or signal alarms when the differential pressure reaches your setpoint. They are single pole, double throw (SPDT) and can be installed to turn one circuit from off to on (normally open) or from on to off (normally closed).
In addition to being UL listed and CSA certified, these switches are CE marked and FM approved, so they also meet European safety standards. They also are IP and NEMA rated for use outdoors and protect against dust and splashing water.
When measuring pressure in ductwork, pair them with a static pressure probe.

Blade-Style Circuit Breakers
Protect against overload and short circuits in low-voltage automotive and other electronic applications. These circuit breakers can replace type ATC, AF, ATO, and 257 blade-style fuses. They are thermal, so they trip when heat is generated by overload current.
Breakthrough current is the maximum current that the circuit breaker can safely stop in the event of a short circuit.
Automatic reset breakers don’t require you to manually reset them after they trip, so they’re good for areas where the breaker isn’t easily accessed. These breakers reset once they cool. However, they will trip repeatedly if the overcurrent condition continues.

Noncontact Flow Transmitters
Using ultrasonic waves, these transmitters measure the flow rate of your liquid from outside your pipe. They're a good choice for applications where you need to retrofit your system or avoid liquid coming into contact with the transmitter. Also known as transducers, these transmitters convert measurements to an electrical pulse that can be interpreted by receiving devices, such as remote displays and programmable logic controllers (PLCs). The pulse outputs match the input voltage of the transmitter. The higher the flow, the more pulses they send. For your receiving device to interpret the signal, you will need to calibrate it for the measurement range and output signal of the transmitter. They only give accurate readings within the rated measurement range. Configure them for either a 4-20mA or digital pulse output when installing.
A digital display makes it easy to check flow rate and configure settings. Clamp these transmitters onto your pipe with the included mounting hardware and gel pads. They measure flow no matter the mounting orientation.
These transmitters are calibrated with water but can be used with other liquids and will generally measure accurately, even if they differ in viscosity and density. You can recalibrate them in the field for accurate readings on pipe and operating conditions.

DeWalt Cordless Freestanding Portable Floodlights
The handle on this floodlight also acts as a stand—pivot it 360° to aim light where it's needed. This floodlight is small and easy to carry to job sites that don't have electrical power service. It has built-in LEDs that last longer, are more efficient, and generate less heat than other light technologies. They cast a cool light that highlights white/blue tones, which is good for inspecting. This light has an impact-resistant plastic lens to protect the LEDs.

Adjustable-beam penlights change from a wide floodlight to a narrow spotlight with a twist of the head.
Penlights with a uniform beam are especially good for close-up tasks and inspection work. Penlights with a bull’s eye beam have a bright center for long-distance illumination.
Styles G and H can operate on either the included rechargeable batteries or standard AAA alkaline batteries.
Note: Battery life is significantly reduced when flashlights are used at the high-beam light setting.
