Platon Glass Tube VA Flow Meter | DS1115

Platon Glass Tube VA Flow Meter - Overview

This Variable Area flowmeter consists of a glass flow tube and float scaled to the flow units required. It also has a frame to provide the end block supports and to cover and protect the tube. The NGX series frames use flow tubes with 100mm long scales, whereas the smaller LGX frames use flow tubes with 30mm scales. To choose a complete flowmeter select the frame code required, and separately specify the fluid flow range needed on the flow tube scale. NGX and LGX series frames are designed to fit your process. The options available allow easy installation as they are surface mounted on a vertical panel. Process connections and labelling can be customised to suit the application. For accurate measurement.

Permanent Ultrasonic Flowmeter | GF U1000 V2

Permanent Ultrasonic Flowmeter - Overview

This permanent ultrasonic clamp-on flowmeter is a cost-effective device that can either be used as a stand-alone meter or as an integral part of a control loop. The GF U1000 V2 Heatmeter (HM) is an ultrasonic permanent clamp-on heat meter/energy meter/BTU meter. The HM is equipped with Pt100 temperature sensors to calculate the energy of a heat-exchanging system. These flowmeters are very simple to install – clamp them onto the pipe, connect it to power and enter the pipe diameter. No expertise or special tools are required. This makes the installation of the sensors in running systems possible as the pipe does not have to be opened. Compact, robust and reliable. Designed for long-term use in industrial applications. The GF U1000 V2 (HM) is specially configured for pure water and can be used on PVDF-ABS, PVC, PP, PE, PB-Instaflex, iron and steel pipes.

Platon Infra-Red Flow Alarm | DS1120

Platon Infra-Red Flow Alarm - Overview

The Platon Infra-Red Flow Alarm DS1120 uses an infra-red beam across the glass flow tube of a Variable Area (VA) flowmeter to determine float position. Passage of the float between the sensor arms is detected, and the sensor determines whether the float is above or below the sensor position. Electronics inside the sensor module give an open collector transistor output, suitable for external logic circuits. Suitable for all gas flows and liquid flows where the float is visible. The sensor is clipped to the back of the flowmeter frame. Movement up and down the frame allows the sensor to provide a flow alarm at any point on the tube scale, as required. The optional mains interface and relay module are used to provide the DC power needed to drive the sensor electronics, plus a SPCO 8 Amp mains relay output. This relay acts as a slave to the transistor output from the sensor module. Each relay module has two output relays and can be used to monitor two separate alarm sensors.

Platon Infra-Red Flow Alarm - Features
- High or low flow arm
- Intelligent: Knows whether float above or below sensor
- Adjustable over full range of flow tube
- Suitable for normal (NG/NGX) or miniature (LG/LGX) flowmeters

No electrical power or external flow measurement input is required as the control system uses the line pressure available. These are ideal for blending or dosing applications to maintain the required delivery of valuable gases or liquids, despite process line pressure changes.

Platon Automatic Flow Controller - Features

Platon Metal Tube GMT Flanged VA Flow Meter | DS1220

Platon Metal Tube GMT Flanged VA Flow Meter - Overview

These variable area meters are made of totally welded stainless steel. The robust construction has no glands or seals to leak which makes the meters suitable for high-pressure applications or extreme temperatures. Liquid flowing up the tapered flow tube lifts the float to an equilibrium position according to the flow rate. A magnetically coupled pointer indicates this flow on an external scale. The large meter indication is easily visible with the pointer moving over a 1500 scale. Each scale is produced specifically for the fluid involved and the process conditions expected. Several flow ranges are available for meters of each standard line size. Meters can be supplied with EN, ANSI or other standard flanges, or BSP or NPT screwed connections. The standard GMT is self-contained and needs no external power. Alternative materials are available for special orders eg. Hastelloy or Monel wetted parts. Brass or Stainless steel bodied meters are also available with screwed connections. The indicator can be provided with one or two flow alarm sensors which are adjustable over the meter operating range. Full electronic transmission and totalisation are available using the “VAMPIRE” electronic module. These flow meters have particular advantages over glass flow meters where fluids are opaque or staining, or where higher safety and security for dangerous or toxic fluids are required.

Platon Metal Tube GMT Flanged VA Flow Meter - Features
- Easy installation—flanged or screwed
- For high pressure or extreme temp applications

Platon Pelton Wheel Flow Meter | DS1010

Platon Pelton Wheel Flow Meter - Overview

This turbine flowmeter operates on the Pelton wheel principle for low flowrate applications on low viscosity fluids. The Pelton wheel retains a manageable diameter allowing close machining tolerances whilst being capable of handling very low flow rates with reasonable accuracy. The units may be used for additive flows, fuel consumption metering, perfumes, colourings etc. A range of interchangeable metering plugs may be provided within one body size, so that flow ranges may be changed very simply. Construction is in stainless steel as the standard but other materials may be used to suit the corrosive properties of the metered fluid. Flanges to ANSI, EN1092-1 or BS10 may be fitted and a design is also available with Ermeto or BSP couplings for high-pressure hydraulic work. The Pelton wheel is a star-shaped paddle wheel housed within a metering plug containing a small jet hole where a high-velocity jet is aimed at the rotor. Rotational speed and hence frequency are directly proportional to flow rate. The sharp edges of the rotor are detected by a reluctance pick-off coil and an alternating voltage is generated.

Platon Pelton Wheel Flow Meter - Features
- Measuring Range: 8 to 1
- Accuracy: ±1.0%
- Repeatability ±0.25%
- Operating Temperature: 150˚C max
