2. GENERAL AND FEATURES
2.1 General Description
The ALTImass series, consisting of a high performance model Type U, a straight-tube model Type S, and
a low-cost, general purpose model Type B, are Coriolis flowmeters capable of measuring mass flows at a
high degree of accuracy. Equipped integrally or separately from the sensor unit is a highly sophisticated
transmitter (self diagnosis feature, large size display, and field reconfiguration capability using a touch panel).
2.2 Features
1. Further improved zero stability over previously offered transmitters
2. Accurate density measurement: ±0.0005g/mL (When measuring liquid with CA003 to CA250 sensor
unit)
3. Fast response: 10 times faster than previously offered transmitters
4. Increased availability output-signal availability
Pulse output (dual outputs), current output (dual outputs), and status output (single output)
5. Reconfiguration of transmitter parameters available with finger touch on the touch panel (also through
communication)
6. Increased self-diagnostic capabilities: cable disconnection check, pipeline vibration check, and
transmitter temperature monitoring,
to name a few
7. Enhanced maintenance functions: error logging and factory default parameter reloading functions
8. 2 alarm indicators equipped
9. Compliant with various communication standards (HART, FOUNDATION Fieldbus, PROFIBUS, Modbus
communication)
10.The measurement of bubble mixed fluid is possible by the adjustment of Gas Multiphase Flow Alarm
(Slug Alarm) which is found in the Self-Diagnosis Function.

NOTES
※1: 1/2" for ASME and JPI flanges.
※2: When wetted parts are made from Alloy C, only screw type connection is adopted as standard.
※3: DIN franges are available only to meters of the wet part material, "SUS316L"and"SUS316L+Alloy C".
※4: For application to foods, this product does not comply with CE marking.
※5: If the viscosity is 10000mPa·s or more, contact OVAL.
※6:
Refer to section 10.5 for the ambient temperature.
※7: This pressure does not represent the rated test pressure of a pressure vessel, but 1/4 of the breakdown test
pressure at OVAL (distorted enclosures do not constitute a failure of the test), or the data obtained from the FEM
analysis, whichever is lower (or safer).
※: For the product compliant with High Pressure Gas Safety Act or CE marking, consult us.
※: Only separately mounted transmitter is applicable.
