METER
THERMAL MASS FLOW METER
Patent #8,021,612
High Performance
ACCU-FLO METER
With an innovative edge, the LANDTEC ACCU-FLO Meter highlights a distinctive feature:
A Zero Calibration User Check. The User Check allows the operator to verify that
their LANDTEC ACCU-FLO Meter has not shifted, drifted or deviated from its original
NIST-traceable Factory Calibration value. This ability makes the ACCU-FLO Meter
unique, extremely useful on Gas-to-Energy projects, environmental compliance
and essential for the carbon credit market.
Factory Approved Field Calibration User Check
Low end Sensitivity (measures as low as 5 SFPM)
5 Year Recommended Factory Service

Technical Specification
LANDTEC’s Thermal dispersion Flow Meter utilizes the constant temperature difference method for
measuring Gas Mass Flow Rate. It contains two reference grade platinum RTD sensors clad in a protective
316 SS sheath. It features direct Mass Flow gases, wide range-ability, low pressure drop and a very low end
sensitivity.
The LANDTEC ACCU-FLO Meter is microprocessor based, does not have any potentiometers, and has
Modbus® RS485 RTU communications.It is powered by 24 VDC (12 VDC, or 115/230 VAC optional). The
power dissipation is under 2.5 watts (e.g. under 100 mA at 24 VDC) for the DC version. The power and
output terminals are in a separate compartment for ease off installation. LANDTEC’s ACCU-FLO METER is
approved.
INTEGRAL
SIP Series
IN-LINE
The ACCU-FLO METER features a dual-compartment enclosure for ease of wiring, OLED display that shows
Mass Flow Rate, Totalized Flow and Temperature. In addition, the calibration milliwatts (mw) feature is
continuously displayed, providing ongoing diagnostics. Outputs include a 4-20 mA signal proportional to
Mass Flow Rate, and Pulsed Outputs of Totalized Flow (24VDC solid state [sourcing] transistor drive), as well
as Modbus® compliant RS485 RTU communications (IEEE 32 Bit Floating Point).
INSERTION
REMOTE
The Flow Element (Integral and Remote, In-line Style) consists of a choice of 316 Stainless Steel Schedule 40
Flow Bodies sized from 1/4” x 6” long to 4” x 12” long. Male NPT ends are standard, with flanged ends tube,
or butt weld optionally available. Note 3” and 4” Flow Bodies have flanged ends as standard.
Mounting
Hardware
(included)
SRP Series
The instrument calibration is NIST traceable and covers a wide variety of gas calibrations. The LANDTEC
ACCU-FLO METER can measure gas flow up to 450ºF (-40ºF to 200ºF standard, up to 450ºF optional on
Remote, Insertion Styles) at pressures up to 500 PSIG (1000 PSIG, optional). Accuracy is +/– 0.5% of Full Scale
+/– 1% of reading with a turndown of 100:1 and resolution as much as 1000:1. Higher accuracy available
with lower turndown (contact LANDTEC).
