Product Description

The sophisticated flow totalizer is an instrument based on ARM microprocessor and cooperates with various flow transmitters and sensors to accurately measure and calculate flow for different fluid media through various flow mathematical models.
It collects, displays, controls, transmits, communicates, prints and processes various signals such as on-site temperature, pressure, flow, etc., forming a digital acquisition system and control monitoring system, which is widely used in trade settlement and factory metering management networks in industries such as petrochemicals, chemicals, metallurgy, electricity, light industry, medicine and urban gas.

Caraterísticas do produto

1. Applicable to a wide range of flow meters and fluid media.

2. Automatic conversion of flow units and automatic calculation of flow coefficient of differential pressure flowmeter.

3. Steam density is calculated according to IAPWS-IF97 formula, and the superheated and saturated states of steam are automatically identified.
