Pulse output flow meters

Pulse output flow meters integrate easily into metering and dispensing systems. Pulse is one of several standard output signals on a flow meter. It comes in two forms: a scaled pulse output, where each pulse equals a fixed volume such as 1 L, and a frequency output, where the pulse rate is proportional to flow rate. Both signals connect directly to PLCs, DCS, batch controllers, flow totalizers, and remote displays.

Pulse output Turbine flow meter

How pulse turbine meter work?

Turbine flowmeter is a speed flow measuring instrument used to measure the flow of fluid flowing through a closed pipeline. A turbine is placed in the center of the pipeline. The two ends are supported by bearings. When the fluid passes through the pipeline, it impacts the turbine blades and makes the impeller to rotate. The rotation velocity of the turbine is proportional to the fluid flow rate; hence the fluid flow through the pipe can be calculated.

Pulse turbine flow meter features

• The pulse flow meter is a speed flow sensor with high accuracy, good repeatability, simple structure, high pressure, wide measuring range, small volume, light weight and low pressure loss. Pulse output turbine meter has fast response for batch control.
• Various sensor sizes: 1/2”, 1”, 2”, 3” or 4”, 8”, 10 inch pulse flow meter
• Inline pulse output flow meter with flange, tri-clover, tri-clamp or thread process connection
• Electronic pulse meter offers one pulse per unit (gallons and litres)
• Pulse output turbine meter option with LCD readout or not.
• NPN pulse output

Pulse turbine flow meter application

Liquid turbine flow meter is used to measure low viscosity, non-corrosive, clean liquid flow, such as water, diesel, gasoline, milk, chilled water, demineralized water, methanol, kerosene, emulsion, glycol mixture and light oil.,etc. water flow meter with pulse output is often requested.
Gas turbine flow meter with pulse output to measure air, N2, natural gas,LPG.,etc

Gear flow meter with pulse output

The gear flowmeter is a new type of digital positive displacement flowmeter, used for precise continuous or intermittent measurement of the flow or instantaneous flow of liquid in the pipeline. It is suitable for the flow measurement of high viscosity liquid such as heavy oil, polyvinyl alcohol, and resin. Each tooth generates a pulse with very high resolution. Hall-effect sensor can measure very small flow rates with ml/min or liter/h flow unit.

Applications of pulse positive displacement flow meter (PD flow meter)

Pulse output PD flow meter can measure kerosene, syrup, resin, grease, refrigerant, polyurethane, brake oil, hydraulic oil, suitable for automobile fuel consumption, boiler fuel, medicine, food, chemical raw materials, wine, milk, vegetable oil canning, etc. 
We can also choose PP material for pulse PD flow meter to measure aggressive liquid, such as sulfuric acid, nitric acid, hydrochloric acid, sodium hydroxide ( NaOH) 

Features of pulse output PD flow meter

• Pulse output type: adopts three-wire system, non-contact square wave output, it is reliable signal transmission and long transmission distance, allowable working voltage DC12V or 24V, and can be used with various secondary instruments, PLC or DCS system connection
• micro flow sensor : 2mm, 4mm,6mm,10mm,1/2”,1 inch. Min flow can detect is 0.6 L/h.
• Pulse output flow meter can also option with LCD display
• Pulse PD flow meter can measure high viscosity liquid, up to 10000 cp
• Option with RS485 or HART protocol
• Remote display options for pulse PD flow meter
