Eletta Flow Meter Catalog: Differential Pressure and Target Flow Monitors for Industry
Quick Answer: The Eletta catalog includes differential pressure and target flow monitors for flow alarm, pump protection, and batching. These instruments suit liquid, gas, and steam lines from DN15 to DN250. For a model and price, send your pipe size, flow range, pressure in bar, and temperature in °C to Silver Automation Instruments.
What the Eletta Flow Meter Catalog Covers
The catalog lists two main product families. First is the differential pressure flow monitor. Second is the target flow monitor. Both types use a direct mechanical sensing element. No control room PLC is required for basic alarm functions.
The differential pressure style works by measuring pressure drop across a built in restriction. The target style measures force on a target disk in the process stream. Both types can trigger a microswitch at a set flow. That makes them useful for low flow cutoff and pump seal protection.
Differential Pressure Flow Monitors
Differential pressure monitors from Eletta are common in steam, compressed air, and cooling water systems. Engineers specify these units when they need a local flow switch without a separate orifice plate. A typical range for water is 1.5 to 15 m3/h on a DN50 line. For air the range can be 30 to 300 Nm3/h depending on inlet pressure.
Most units accept process temperatures up to 120 °C as standard. High temperature versions can handle 200 °C. Process connections include 1/2 inch BSP, 1 inch NPT, and PN16 flanges. Wetted parts can be brass, stainless steel 316, or PTFE coated alloy.
We have seen these monitors used on boiler feedwater lines in Southeast Asia and on compressor cooling loops in Australia. They work well because the response is direct and does not depend on an external power supply for the switching function.
Target Flow Monitors for Difficult Fluids
Target flow monitors are selected when the liquid is dirty, sticky, or has high viscosity. The target sits in the flow path and moves with changes in flow force. This design tolerates particles better than an orifice edge. Applications include fuel oil lines, pigment slurries, polymer melts, and brine.
A customer in Vietnam asked us about a paint line. They wanted a simple low flow alarm for a solvent recovery line. The fluid had solid residues. We recommended a target flow monitor with a stainless steel target and PTFE seal. It replaced an inline rotameter that needed weekly cleaning.
Because the target monitor has a direct mechanical link, it can operate without a separate transmitter. Optional 4-20 mA output is available for remote monitoring. ATEX Zone 1 models are also listed in the Eletta flow meter catalog for gas and solvent environments.
Output and Switching Options
Eletta differential pressure and target flow monitors can include one or two microswitches. The switch rating is typically 5 A at 250 V AC. For continuous 4-20 mA output, a transmitter version is available. The HART pr
Most engineers skip the 4-20 mA option when the only task is pump interlock. The switch output is simpler and faster to commission on site. If you need both local alarm and remote signal, specify the transmitter version from the start.
Industry Applications
The Eletta flow meter catalog is used in water and wastewater plants, chemical processing, food and beverage lines, oil and gas, and marine systems. In a desalination plant in Oman, the differential pressure monitor protects high pressure pumps on the brine line. In a food processing plant in Thailand, a target flow monitor triggers a CIP water alarm on a syrup line.
For gas applications, differential pressure units are installed after pressure reducing stations. For liquid with suspended solids, target units are preferred. The choice depends on fluid type, pipe size, pressure drop allowed, and fail safe action.
How to Select an Eletta Flow Monitor
Start with four data points. Pipe size in DN, flow range in m3/h or kg/h, process pressure in bar, and process temperature in °C. Then define fluid type and viscosity. For water and clean gas, a differential pressure monitor normally fits. For viscous or particle loaded liquids, a target monitor is better.
Send these data to Silver Automation Instruments. Our engineers check the Eletta flow meter catalog and select the right model code. That step saves time because the model code includes body material, connection size, seal material, switch option, and approval. A quotation normally returns within one working day.
FAQ
What is the difference between an Eletta differential pressure flow monitor and a target flow monitor? A differential pressure unit uses a built in restriction and measures pressure drop. A target unit measures force on a disk in the flow. Target units handle dirty or viscous flow better.
Can Eletta flow monitors handle steam? Yes. Differential pressure monitors are common on steam lines. Check temperature and pressure limits first. High temperature models cover up to 200 °C.
Do these devices need a power supply? The microswitch versions do not need a power supply for switching. The 4-20 mA transmitter version needs 24 V DC loop power.
Are ATEX versions available? Yes. The Eletta catalog includes ATEX Zone 1 options for gas and solvent environments. State the zone and gas group in your inquiry.
What is the typical delivery time for Eletta flow monitors in Southeast Asia and Australia? Standard models often ship in 2 to 3 weeks. Special material or ATEX versions can take 4 to 6 weeks. Confirm the lead time with Silver Automation Instruments after model selection.
