STEAM FLOW COMPUTER (SATURATED STEAM SERVICE)

Format:EL4101

Using the most advanced electronic technologies, this digital instrument has been developed specifically to meet the most demanding steam flow measurement applications where accuracy is the prime
requirement.
In response to flowrate and temperature information arriving from the sensing terminal, such as a Vortex flowmeter, it calculates “dryness factor of 1” saturated steam flow, transforms it to mass and calorie, and totalizes the flow.
It also provides a totalizer pulse output and an instantaneous flowrate analog output (mass equivalent).

FEATURE

1. By simple key operations or by inserting an IC card in the slot, parameters such as meter factor, temperature and pressure ranges and other parameters in the connected flowmeter can be easily changed.
2. Built around a microprocessor, the instrument carries out calculations entirely in digital signal processing circuits to achieve high degree of accuracy and reliability.
3. Variables such as temperature and pressure can be reviewed on command with the front panel keypad even during operation.
4. A nonvolatile memory (E 2 PROM) retains all parameters and variables. Totalized value can be reset upon power depending on setting.
