Warning - Read this first
Compressed gasses can be dangerous!
Please familiarize yourself with
the forces under pressurized conditions. Respect the local guidelines and
regulations for working with pressurized equipment.
Gas flow through pipes follows certain physical laws.
These physical
laws have serious consequences for the installation requirements. Familiarize
yourself with the basic physical laws of flow measurement, to make sure that
the product is installed correctly. Always make sure that upstream length,
downstream length, flow, pressure, temperature and humidity conditions are
within specifications.
Precision instruments need maintenance.
Check your flow meter
regularly and make sure it remains clean. When polluted, gently clean the
sensor using demineralized water or cleaning alcohol.
Precision instruments need regular re-calibration.
To keep your
VPFlowScope probe in best shape, it needs recalibration. We advice annual
recalibration.
Not intended for fiscal metering or billing.
Our flow meters are not
certified for fiscal metering. Laws on fiscal metering and billing may vary per
country or state.
Do not overestimate the results. VPInstruments does not take any
responsibility for the correctness of measurement results under field
conditions.
The practical measurement uncertainty of a flow meter in the
field may vary, depending on how well it is installed, due to the nature of gas
flow. The piping table provides guidelines on how to optimize the field
accuracy. Our products are not intended to be used as a single means to
determine compressor capacity.
Do not open the device.
Our instruments are assembled with high
precision. Opening this device is dangerous and may destroy the
instruments. Warranty is voided when you open the instrument.
