2. Current clamp - Wikipedia

   en.wikipedia.org/wiki/Current_clamp

   An electrical meter with integral AC current clamp is known as a clamp meter, clamp-on ammeter, tong tester, or colloquially as an amp clamp. A clamp meter measures the vector sum of the currents flowing in all the conductors passing through the probe, which depends on the phase relationship of the currents. Only one conductor is normally ...

3. Air flow meter - Wikipedia

   en.wikipedia.org/wiki/Air_flow_meter

   An air flow meter is a device similar to an anemometer that measures air flow, i.e. how much air is flowing through a tube. It does not measure the volume of the air passing through the tube, it measures the mass of air flowing through the device per unit time, though Thus air flow meters are simply an application of mass flow meters for the ...

4. Utility submeter - Wikipedia

   en.wikipedia.org/wiki/Utility_submeter

   [citation needed] The approach makes use of individual water meters, gas meters, or electricity meters. Sub-metering may also refer to the monitoring of the electrical consumption of individual equipment within a building, such as HVAC, indoor and outdoor lighting, refrigeration, kitchen equipment and more.

5. Current transformer - Wikipedia

   en.wikipedia.org/wiki/Current_transformer

   Many digital clamp meters utilize a current transformer for measuring alternating current (AC). Current transformers are used extensively for measuring current and monitoring the operation of the power grid. Along with voltage leads, revenue-grade CTs drive the electrical utility's watt-hour meter on many larger commercial and industrial supplies.

6. Flow measurement - Wikipedia

   en.wikipedia.org/wiki/Flow_measurement

   When choosing a meter for an application that requires particulate flowing through the pipe, it is best to use a meter without moving parts such as a Magnetic flowmeters. Fire meters are a specialized type of turbine meter with approvals for the high flow rates required in fire protection systems.

7. Duct leakage testing - Wikipedia

   en.wikipedia.org/wiki/Duct_leakage_testing

   A duct leakage tester is a diagnostic tool designed to measure the airtightness of forced air heating, ventilating and air-conditioning (HVAC) ductwork. A duct leakage tester consists of a calibrated fan for measuring an air flow rate and a pressure sensing device to measure the pressure created by the fan flow.
