The Weber flow-captor represents a family of a comprehensive and versatile range of calorimetric flow meters and switches. Calorimetric sensors are nonmechanical devices for the detection of flow of pasty, liquid or gaseous substances. 'Calorimetric' comes from the fact that heat energy is used to produce electrical signals that are proportional to the actual flow rates.
Benefits of calorimetric sensors over mechanical devices
The devices have no moving parts, this means that while other traditional devices - like paddle switches or turbine-switches - contain mechanical elements that are subject to wear, flow-captors do not. The result is optimum reliability and a long life span.
Calorimetric sensors are nonintrusive introducing no backpressure. Any measurement of the flow upstream of the flow-captor will be exactly the same as downstream.
Transistor outputs suffer no mechanical wear, offering a reliable switched-pulse output technique - and active temperature compensation ensures considerably reduced temperature drift. All this results in a reliable and precise flow sensor that is up to date with current technology.
Applications where these sensors would be suitable include:
* Water/wastewater: Monitoring the flow of water through filter stations, protection of pumps from 'dry run', controlling water intake in desalination plants.
* Paint manufacturing: Monitoring of material flow into mixing tanks, control of agitation in mixing tanks.
* Automotive: Detect nozzle clogging in paint spray booth, monitor flow of cooling water in engine test rigs, monitoring of coolant flow on large diesel engines etc.
* Sprinkler systems: Monitor mixing of water and foaming agents.
* Cement plants: Control of cooling circuits in cement crushers.
* Machinery: Control of coolant flow in tooling machines.
* Steel mills: Control of recycling pump in pickle tanks, control of process cooling water, monitoring of lubrication systems and reheat furnace cooling water systems.
Benefits of the captor flow sensor products:
* Easy installation - Set up and adjustment: (Less than 2 min to make any adjustment).
* Accuracy at low flow rates - Weber offers high precision in the lower flow area.
* High repeatability - The setpoint for an alarm signal will always trigger the device precisely at the same flow value - essential for repeatable performance.
* Sealed and potted housing - this gives a package that is shock, vibration and tamper proof.
* LED Display for actual flow, setpoint and output status, offering at a glance, immediately recognisable operating conditions.
