Metal Tube Purge Flowmeter | Platon DS1210

Metal Tube Purge Flowmeter - Overview

Ideal for liquid or gas flow monitoring on small lines in purging, mixing or sampling systems. It uses a stainless steel tapered tube to create a variable area flowmeter. The magnetically coupled pointer shows flow rate on an external scale. Metal Tube Purge Flowmeters are used where the higher integrity offered by a metal flow tube is important, or where conventional glass flow tubes are not allowed in the process. The meters are available with inline (API) or rear-facing (APT) screwed connections. For fine flow rate adjustment, the APV model has an integral multi-turn needle valve. Scales are individually produced to show the actual fluid flow for the process fluids and conditions relevant. The units are suitable for flush mounting in a control panel, using a simple mounting kit. Standard units require no electrical connection.

Platon Safety Housed GU VA Flow Meter | DS1111

Platon Safety Housed GU VA Flow Meter - Overview

Type GU are glass tube Variable Area Flowmeters for the direct display of liquid or gas flow rate. It has a robust rigid frame which is suitable for mounting directly into plant pipework, protecting the glass tube from pipework stress and random plant damage. The safety Perspex window gives good flow visibility whilst protecting the operator. A safety blowout disc on the rear of the housing provides a relief vent for process fluids, in case of glass tube damage. Glass tube VA flowmeters are simple and reliable in operation, and instantaneous in response. They offer flow visualisation to the operator, and the float rotation confirms correct meter performance. Standard tubes and floats offer low line pressure loss and a high resolution 100mm linear scale, fused into the glass tube. Fluid flows vertically upward through the tapered glass tube which causes the float to rise to an equilibrium position. Flow rate is measured on the scale of the flow tube, along the top edge of the float. The borosilicate glass tubes are individually scaled according to customers' requirements, and individually flow calibrated.

Platon Safety Housed GU VA Flow Meter - Features
- Safety housed for operator protection
- Site interchangeable 140mm flow tubes
- Robust construction
- Instant flow rate visual indication
- Suitable for installation in unsupported pipework

Screwed Metal Tube VA Flowmeter | Platon DS1221

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.
