Airflow & Differential Pressure Measurement

Home / Services / Airflow & Differential Pressure Measurement

An Air Flow Meter measures air velocity as well as air pressure. Depending on the type of application, the Air Flow Meter is made as a hot-wire Air Flow Meter, a vane or cup anemometer, a Pitot tube air flow meter or a pocket weather flow meter, all of which can measure air velocity and some also measure air pressure, temperature, dew point, humidity, static/differential pressure and detect the wind direction.

Air Flow Meters are essentially mass flow meters, as they determine the air velocity and air pressure by measuring the mass flow of a medium, in this case, air, which is a critical component when assessing an HVAC system as it determines energy efficiency, balance and cost effectiveness of the installation, be that microbiological safety cabinet, laminar flow, work station or local exhaust ventilation system.

Our vane anemometer with a 100mm diameter functions by the air stream hitting the vane making it rotate detecting the speed through the built-in magnetic sensor, this is converted in to metres per second (m/s), its onboard computer allows average airflow velocities and temperatures to be logged and recorded accurately.

Our Core Services


Biological Safety Cabinets offer protection from microbiological contamination to the operator, environment and product. They are utilised by a range of scientific and research facilities within the commercial and non-commercial sectors, including clinical research, defence, education and general healthcare sectors.


Having the correct laminar air flow equipment in your cleanroom environment is very important, so British Clinical Services have worked hard to amass a quality selection of high-end equipment manufacturers for your needs.


Ductless fume hoods do not require any external ventilation. Instead, they use filters to capture solvent fumes from circulating air, which is then vented into the room. Ductless fume cabinets can maintain the same airflow as a standard vented fume hood but are easier to install as they do not require ventilation ducts.


Contamination control and PCR process repeatability is simplified with a range of PCR Cabinets. Each PCR Cabinet we install provides filtered vertical laminar flow to purge the work area of contaminants between amplifications and during preparatory procedures.


All fume cupboards and ventilated enclosures should be monitored and serviced annually both for safety and compliance purposes but also to retain the efficiency of your units.

British Clinical Services offer comprehensive maintenance and servicing agreement for all makes and models of Fume Cupboards.
