Screwed Metal Tube VA Flowmeter – Overview

This flowmeter is ideal for industrial use as an alternative to large glass tube flowmeters. Suitable for gas or liquid flow measurement at high pressures and temperatures, where the fluids are opaque or dark-coloured. It also provides high operational security for dangerous or toxic materials. Models GMTB and GMTS are brass or Stainless Steel tube flowmeters with female screwed connections. With 1/2”,1” and 2” BSP/NPT threaded fittings standard. The VA meter principle used in the Platon GMT flowmeter measures the position of a float in a precision-machined tapered tube. The float rises with the flow up the taper until the upthrust from the flow balances with the weight of the float. A magnet, electron beam welded into the float casing, drives the external meter indication over a 100mm scale typically displaying a 10:1 flow range. Options available on the GMTB/GMTS include (GMTA) flow alarm outputs for high or low adjustable set points and electronic 4-20mA flow transmitter (GMTX) outputs. All of these are available with CENELEC approval. All units are calibrated for the specific line conditions or fluid involved.
