The Advanced Sensor Design’s Mud Flow Transmitter is an innovative vane-type (paddle) meter that measures mud flow through the drilling mud inflow or outflow pipe. It mounts on the inflow or outflow line with the vane immersed into the mud flow.
The packaging of the Advanced Sensor Design MFT is rugged and durable. Our design eliminates the problems normally associated with vane-type flow meters, namely the mechanical linkage with a potentiometer or encoder. The low-power consumption gap sensor is rated for hazardous locations with ATEX pending for intrinsic safety areas according to EEX ia IIC T4/T6, and UL and CSA pending for Class 1, Divsion 1, Groups A-D intrinsic safety areas according to NEC Article 505.
What makes the Advanced Sensor Design MFT unique and beneficial is the use of a cam that varies in distance from a fixed non-contact measurement sensor as the paddle is displaced by the variable mud flow. The gap variation between sensor and cam is measured electronically, linearized, and calibrated for mud flow rate.
