meters uk Ltd™ Utility Meter Manufacturers Steam Meters
For precision flowrate metering of liquids, gases and steam.
The TRIO-WIRL® VT/ST is a measurement system in a 2-wire design with a DSP controlled converter in a compact design. The standard metering systems include a two line LC-Display for indicating the flowrate and totalizer values. The converter can be used in simple dialog using the 3 magnetic sensors.
The TRIO-WIRL® VR or SR expand the metering system by adding a remote mounted converter design. This design is based on the VT/ST and therefore provides the user with identical functionality, while at the same time allowing the converter to be installed remotely (up to 10m away) where accessibility would otherwise be difficult. Suitable for ambient temperatures up to 70°C.
In addition to the 2-wire designs of the VT/ST and VR/SR models, a 4-wire version is available in the TRIO-WIRL® VM/SM. The VM/SM converter offers numerous options for solutions to very demanding flowmetering requirements.
