Flow totalizer

Product Details

I. Overview

The XMJB flow totalizer can accumulate the mass, volume, and length of the calculated material, and can also be controlled in batches. The meter has high reliability and strong anti-interference ability. Programmable input specifications, and input three signals of temperature and pressure flow. In terms of output, we adopt a modular structure design, which can alarm the upper and lower limits of pressure, instantaneous flow and temperature, and has various functions such as communication, transmission and distribution output.
In addition, the temperature and pressure compensation function can realize the temperature and pressure compensation operation of saturated steam, general gas, superheated steam and liquid through programming. The look-up table method has higher accuracy when compensating for steam. Moreover, the compensation formula can be extended according to user requirements to achieve special functions, such as accumulation of heat or other physical quantities.

When the meter is used as a batch controller, it has an independent 4-bit control accumulator and a 12-bit total accumulator, and a dedicated display state, which is powerful and easy to operate.
