Ufm/universal flow monitors flow switch MN-DSF300LM-16-1050

UFM flow switches are developed and produced by Universal Flow Monitors, Inc., a US based company founded in 1963. Initially focused on manufacturing flow switches for the automotive industry, the company has now expanded to industrial sectors such as petrochemicals, wastewater treatment, and energy. The product adopts mechanical structure designs such as blade type and piston type, with on-site flow indication and adjustable alarm function. The maximum working pressure reaches 2000PSIG, suitable for monitoring various media such as water, lubricating oil, compressed air, etc. [2] [4]. Its MN series, LL series, etc. cover a flow range of 2-600LPM and have passed international certifications such as CE and CSA. Original factory warranty services are provided by agents such as Kuerz Instrument (Shanghai) Co., Ltd. in the Chinese region

LL/LP/LH series: piston type low flow design, flow range 0-20LPH to 0-75LPM, dedicated to low flow media such as lubricating oil and compressed air [2]

MX/SX series: corrosion-resistant products, PVC or polysulfone material shell can resist acidic liquid erosion, hydraulic capacity 100-200 PSI

Technical Parameter

Fluid temperature adaptation range: -40 ° C to 200 ° C, accuracy up to ± 2% full scale

Mechanical switch triggering response time ≤ 2 seconds, electrical parameters can be selected as 4-20mA or 24VDC output

The process interface includes various specifications such as NPT and SAE flanges, and the sealing components are made of butadiene rubber or fluororubber material

Application scenarios

Steel industry: used for measuring cooling water flow and low liquid level alarm in rolling steel systems, such as the application case of Baoshan Iron and Steel Co., Ltd

Petrochemical industry: Monitor abnormal flow in oil pipelines and trigger shutdown protection to prevent equipment from running dry

Wastewater treatment: paired with Insite ? Transparent flow indicator, real-time display of deionized water and dilution chemical flow

Working principle

Adopting a piston or blade mechanical transmission structure, when the fluid pushes the piston/blade, the spring resistance and fluid dynamics form a dynamic equilibrium. The piston displacement is converted into linear motion through a conical shaft, which drives the pointer to display the flow rate value. The preset alarm point is activated by a micro switch to achieve contact on/off, triggering the action of the external control system

The UFM compact ultrasonic flowmeter is a low-cost external clamp type ultrasonic flowmeter. The UFM model realizes the transmission time difference and measures the flow in the pipeline in a non-invasive manner. It is a compact and lightweight design with easy installation features, all integrated into one clip on unit. This device can measure velocity and flow in pipelines with an outer diameter range of 0.98 to 4.62 inches (24.89 to 117.35 millimeters). The screen provides easy to read text and convenient backlighting for visual comfort. This model is equipped with volume pulses and 4 to 20 mA flow output.

UFM piston variable area flowmeter

Variable area flow meters are used to monitor the flow of clean fluids such as water, oil, chemicals, saltwater, deionized water, and paint. Provide the following options or combinations

A simple mechanical flow indicator switch with a 420mA transmitter and RT for visible LCD display of local chemicals. For saltwater, a special device that is permeable or oily is generally used to order oil according to the fluid number

UFM piston flowmeter product PI series description

The piston flowmeter PI series/column variable area flowmeter places an orifice plate on the conical shaft to determine the flow rate. They can be installed at any position on the pipeline. There is no need to arrange straight pipe sections before and after the flowmeter. The mechanical sensing system directly drives pointers, switches, and transmitters. All flow meters are calibrated separately for specific liquid viscosities.
