Ratemeters & Totalizers

ratemeters
912-MC

Ratemeters and totalizers are utilized for rate, total, or blending applications. This is a general-purpose instrument that conditions the electrical signal generated by the flow meter and scales the resulting flow information into a flow rate and flow total display in the units of measure desired by the end user. Additional functionality such as alarms, analog output, pulse output, and serial communications may also be provided.

Ratemeters and totalizers are available to work with most flow meter types and the most common electrical signals produced by flow meters. In some cases, an amplifier or signal conditioner may be necessary. Non-linearity corrections are available in some units. Separate K-factors (calibration points) can be programmed to compensate for changes in K-factor with flow rates. Linearization is useful in improving the accuracy of the flow meter.

Serial communication is used to transmit information between two computers or between a computer and a printer. There are several commonly used standard hardware interfaces such as RS-232, RS-422, and RS-485. There are also a variety of communication protocols, or message formats, which are used.
