K-MVT Multivariable Transmitter Communications Interface Module

Weatherford’s K-MVT multivariable transmitter (MVT) communications interface module (CIM) applies proven “smart” technology to simultaneously measure three independent variables for gas or water flows. The K-MVT technology provides fast, audit-quality measurement of differential pressure, static pressure, and temperature. It can be used as a gas-flow transmitter for orifice and V-Cone® meters and also as a water-flow transmitter for V-Cone meters. The K-MVT module can be built into the enclosure system of a Weatherford remote terminal unit (RTU) but is also available as a stand-alone, explosion proof module.

Microprocessor-based electronics, coupled with sensor characterization, improve temperature and pressure compensation to enhance accuracy. The microprocessor performs one-second measurement averages and flow extension calculations to make readings available to a K-500, K-2000, or K-3000 RTU, allowing the RTU to produce flow calculations that meet the quality requirements of custody transfer. The RS-485 multi-drop serial communications interface allows up to four MVTs to communicate with a single RTU.
