LRM800 Leak
Rate Monitor
The LRM800 Leak Rate Monitor is designed to meet
the needs of
nuclear power plant technicians for a portable device to perform leak
rate testing of penetrations. Using a source of pressurized air, one
side of the penetration is brought to test pressure. The air mass flow
rate to maintain test pressure is measured.
The
LRM800 incorporates Teledyne Hastings HFM-200 and/or HFM-201 mass
flowmeters. From one to four flowmeters may be used to cover the
required range. Full scale ranges of 10 SCCM up to 100,000 SCCM are
available. Typically, a separate flowmeter is used for each order of
magnitude. |

Published accuracy of the HFM-200 and HFM-201 is
1% of full scale.
However, the LRM800 implements fifth-order polynomial curve fitting to
give improved accuracy.
Features:
- 10"W x 16"L x
11.5"H aluminum case, with removable hinged lid and carrying handle
- 90 to 264 VAC, 47 to 63 Hz power input
- Internal sealed lead-acid battery with charger,
for up to 11 hours of operation on a charge
- 2 line x 16 character alphanumeric LED display
of range and flow
- Solenoid valve range selection
- Backflow water trap on outlet to prevent damage
to LRM if there is water in the penetration
- 3/8" Swagelok QC6 quick connect fittings for
instrument air and penetration flow lines
- External calibration fitting for supply side
calibration
- RS232 serial I/O
The LRM800 is not stocked, but is configured and
assembled to meet the customer's specifications. Custom configurations,
such as higher flow rates, can be provided.
