Hedland Flow Meter PDF Data Sheets: Technical Breakdown of Threaded High-Pressure Sensors
Quick Answer: Hedland flow meter PDF data sheets for threaded high-pressure sensors list port thread type, working pressure, burst pressure, wetted parts, and accuracy. Use those values to shortlist meters for hydraulic oil, fuels, and process water lines above 100 bar. Silver Automation Instruments can match the same thread and pressure specs to a meter from our range and quote within one working day.
What Engineers Check First in a Hedland PDF Data Sheet
Most engineers download Hedland PDF data sheets to check three things. Port thread type, maximum pressure, and accuracy at a given viscosity. In practice the data sheet does not always show installation limits. That is where we help. We have seen customers in Southeast Asia order the wrong thread type because one page listed both NPT and BSPP options without a clear default.
Threaded High-Pressure Sensor Specs That Matter
Threaded high-pressure sensors are normally listed by port size from 1/4 inch NPT up to 1 inch NPT. Some models also show SAE J1926 straight thread or BSPP options. The pressure rating often appears as working pressure and burst pressure. A common high-pressure unit shows 420 bar working pressure and 690 bar burst pressure. Accuracy is typically 2 percent of full scale for oil and water. Wetted parts are often brass, stainless steel, or aluminium with Viton or EPDM seals. The temperature range often runs from minus 29 C to plus 120 C.
Most data sheets also show flow range in L/min or GPM for each port size. Viscosity limits appear in centipoise or Saybolt Universal Seconds. Read both columns before you shortlist a meter.
Installation Limits Not Clear in the PDF
Threaded high-pressure sensors need straight pipe runs to avoid turbulent flow. The PDF may specify a viscosity limit. It may not state the minimum straight run. In practice we recommend 10 diameters upstream and 5 diameters downstream for positive displacement and turbine meters. Use thread sealant rated for the fluid. Do not use PTFE tape on oxygen lines. Pressure spikes from pumps can exceed the rated working pressure. A flow meter rated for 420 bar can still fail early if the system sees water hammer at 600 bar. We have seen this on hydraulic test benches in Malaysia.
Matching Hedland Threaded Sensors to a Silver Instruments Meter
Silver Automation Instruments supplies threaded high-pressure flow meters for liquids and gases. Our oval gear flow meter works well with hydraulic oil, diesel, and fuel oil from DN4 to DN50. Pressure ratings go up to 250 bar standard and 400 bar with special options. Outputs include 4-20 mA HART, pulse, and Modbus RTU. A paint manufacturer in Thailand replaced a variable area unit with our oval gear meter because the plant needed a 4-20 mA signal to the PLC. The meter had a 1/2 inch
Last year a customer in Vietnam ordered two oval gear meters for hydraulic oil at 250 bar. They used DN15 threads and 4-20 mA HART output. The meters were calibrated at 45 cP and 20 L/min. The order shipped in seven days.
For conductive liquids like water, acid, and brine, electromagnetic flow meters can handle pressures up to 40 bar in standard designs. For corrosive chemical injection at high pressure, we offer ultrasonic clamp-on meters that do not touch the fluid. These meters avoid the threaded port entirely. They are not always right for low flow below 0.1 m/s. So the data sheet matters.
How to Read a Hedland PDF Data Sheet Without Missing Anything
Start with the pressure drop curve. Then check the viscosity correction. Then look at the repeatability number. Most engineers skip this part. The pressure drop curve tells you if the meter will choke a pump at maximum flow. A 1/2 inch threaded flow meter at 40 L/min can add 3 bar of pressure drop. At 60 L/min the same meter can add 5 bar. The PDF often shows this in a small chart on page two.
FAQ
What does a Hedland threaded high-pressure sensor data sheet show?
It shows port thread type, working pressure, burst pressure, accuracy, wetted parts, temperature range, and flow range by viscosity.
Can Silver Instruments supply a flow meter with the same thread size as a Hedland unit?
Yes. Send us the data sheet or the thread callout. We can match NPT, BSPP, SAE, or flange connections. Specify DN, pressure, and fluid type.
What is the typical accuracy for threaded high-pressure flow meters?
Most variable area and oval gear designs show 2 percent full scale or 0.5 percent of rate. Positive displacement meters from Silver can reach 0.2 percent of rate for oils.
Which flow meter type works best for high-pressure hydraulic oil on a test bench?
Oval gear meters with stainless steel or aluminium bodies perform well. We recommend a meter rated for at least 1.5 times the maximum pump pressure. Add a pressure relief valve if the system has hammer.
What should I send for a fast quote?
Send us your pressure in bar, temperature in Celsius, pipe size DN or NPT, flow range in L/min or kg/h, viscosity in cP if known, and required output signal. We reply within one working day.
