Biogas measurement provides gas quantity output data, detects the efficiency of a fermentation tank, controls combustion efficiency of the boiler and monitors greenhouse gas emission (CH4 and CO2).
Raw Biogas is usually measured with a low flow rate and pressure of 50-60 mbar and an ambient temperature rising to 50°C after fermentation. Water-saturated biogas can cause 5-6 vol % liquid water in the pipe after cooling down. Particles can cause clogging. Water vapor and H2S forms a corrosive acid. Backflow and scaling of bacteria may appear. Hazardous area certification is required.
In coating facilities for beverage cans, cars, truck bodies, etc. air flow velocity needs to be measured accurately at different points:
Ultrasonic transit time flowmeters measure the flow velocity by 2 transducers clamped on outside the pipe for sending and receiving ultrasonic signals:
Diaphragm seals are used to protect pressure instruments from corrosive, viscous, clogging or hot process media and safeguard highly hygienic and ultra pure liquids from contamination.The seals and membranes are customized for a variety of applications with different materials, coatings and linings, mounting and connection types.
