          These units are designed to measure the flow rate of superheated steam & saturated steam in mass or in terms of normalized volume. These flow meters compute compensated steam flow by receiving input from Vertex flow meter, volumetric flow, Orifice plate, ISO 5167 computation, Venturi & Vereabar computations. It computes instantaneous density from pressure & temperature signals as per ASTM norms & computes the mass flow. These instruments can easily interfaced to SCADA or DCS systems with various options like analog signal retransmission and RS-485 MODBUS output. .
► Multi Parameter Auto scroll display like Steam press., temp., Nm3 and Sm3
► The instrument can be configured to work on SATURATED or SUPERHEATED or BOTH.
► Non-volatile memory to retain totalized flow, no need of battery to change.
► Gives efficient Pressure and Temp. Compensations for mass flow calculation.
► Calculates Flow rate in NM3/Hr or SM3/Hr as selected.
► Liner or square root input selection with 0.1% Accuracy.
► Isolated 0/4-20mA retransmission output proportional to standard flow rate.
► Field operated user friendly menu for device configurations & calibration.
► 8/10 digit Flow Totaliser with password protected reset.
► Fully password protection for tamper free operation.
► Isolated High speed communicative serial interface facility (RS-232/485).
► 2 nos. 24 Volt loop power supply for Flow & Pressure Transmitter.
► Optional GSM mobile connectivity for wireless Remote access (SMS).
► Flow Meter computer software available.
► Weather proof or flame proof housing.
► Linear or square root option and automatic unit changable.
Suitable for orifice and vertex flow meters Flow managements Computer software available.
