Can a mass air flow sensor cause a cylinder misfire?
If an oxygen sensor or mass airflow sensor is failing, it could give incorrect data to your engine’s computer, causing the misfire. When a vacuum line is broken, it can cause a fuel-injected motor to misfire. Replacing a vacuum line that’s gone bad can potentially resolve the misfire.
What kind of flow meter does fire research use?
Fire Research Corporation manufactures flowmeters and pressure indicators specifically designed for use on fire apparatus and in the fire services. DataTron FlowTester – The FTC200 DataTron is a 4-channel, portable sampling Flow and Pressure Meter for GPM/LPM (Flow) and kPa/PSI (Pressure) display.
Why are there bubbles in my flow meter?
AIR BUBBLES When dealing with an open system, it is possible for air to be introduced into the system during liquid intake. Air or impurities that have blended into the liquid cause bubbles. For a vortex flow meter, these bubbles disturb the creation of Karman vortices.
What causes slurry detection on a flow meter?
With an electromagnetic type flow meter, wear and clogging are minimal due to the free-flowing structure of the unit. Slurry detection is also possible using Coriolis type flow meters. 6. AIR BUBBLES When dealing with an open system, it is possible for air to be introduced into the system during liquid intake.
Where is the purge meter located on a fire pump?
1. Close system OSY valve “A” 2. Open by-pass valve and “B” butterfly throttle valve 3. Purge meter, located on venturi, as follows: a) Open station shut-off valves on venturi & vent valves attached to meter. When a steady stream of water passes through hose, meter is purged of air. b) Close the vent valves after purging.

What can a portable flowtester be used for?
Portable FlowTester – The Portable FlowTester is available for flow or flow and pressure testing. It will display flow rate directly in GPM or LPM. FlowTesters can be set-up for pressure testing in psi, kPa, or bar. Use it to calibrate fire suppression equipment, test pump effectiveness, test hydrant flows, and teach hydraulics.
Can a flow meter be affected by air bubbles?
For an ultrasonic flow meter, they inhibit the propagation of ultrasonic waves. Both cases result in malfunctions. Since Coriolis type flow meters measure mass flow, they are unaffected by air bubbles. For electromagnetic type flow meters, bubbles can cause unstable flow readings.
