Flow Meter Spec Technical Sheet: Sourcing Electromagnetic and Multi-Jet Water Meter Specs
Quick Answer: Silver Instruments supplies electromagnetic flow meters from DN10 to DN2000 and multi-jet water meters from DN15 to DN50. Send your pipe size, flow range, pressure and temperature to get a technical sheet and price quote within 24 hours. Our team works with water utilities, desalination plants and industrial OEMs across Southeast Asia, Oceania, Latin America, Africa and the Middle East.
Engineers and buyers often start with a simple question. What data must I collect before I source a water meter? The answer is not complicated. You need the pipe diameter, the normal and maximum flow rate, the fluid type, the pressure, the temperature and the required output signal. Without these values you cannot compare electromagnetic and multi-jet meter specs properly.
Electromagnetic Flow Meter Specs That Matter
Silver Instruments AMF series electromagnetic flow meters cover DN10 to DN2000. The minimum fluid conductivity is 5 µS/cm. Standard accuracy is 0.5 percent of reading. Optional accuracy reaches 0.2 percent for custody transfer or dosing applications. The PTFE lining handles temperatures from -20 °C to 120 °C. Hard rubber lining suits ambient water up to 80 °C. Electrode materials include 316L stainless steel, Hastelloy C, titanium and tantalum. Titanium is the right choice for seawater and brine. Hastelloy C works for many acids. 316L stainless steel is fine for clean water and wastewater.
Output options include 4-20 mA, pulse, RS485 and HART. Power supply can be 220 V AC or 24 V DC. Flange standards cover ANSI, JIS and DIN. Protection rating goes up to IP68 for submerged installations. Many plants request IP67 as a standard because it avoids expensive housing. Electromagnetic meters need a straight pipe section. Keep 5D upstream and 2D downstream from the sensor. These installation details belong on any technical sheet. They affect accuracy more than many buyers expect.
Multi-Jet Water Meter Specs That Matter
The Silver Instruments multi-jet water meter line covers DN15, DN20, DN25, DN32, DN40 and DN50. Typical accuracy follows Class 2 under ISO 4064. R values go from R80 to R160 depending on the model. The body is brass or engineering plastic. Standard pressure rating is PN16. Cold water versions handle 50 °C. Hot water versions handle 90 °C. Thread connections are common for smaller sizes. DN15 uses G3/4. DN20 uses G1. DN25 uses G1 1/4. Pulse output is common for building management and remote reading systems. M-Bus and RS485 are also available for larger property networks.
We see many orders from residential compounds and small factories. A water utility in the Philippines recently sourced 300 DN20 multi-jet meters with pulse output. They needed the pulse value in liters per pulse. Our technical sheet listed
Electromagnetic or Multi-Jet: Which One Should You Source
Choose an electromagnetic flow meter when the liquid is conductive, the pipe is large or the solids content is high. Wastewater, river water, seawater, sludge and chemical dosing lines are typical examples. Choose a multi-jet water meter for clean cold water in smaller pipes. Multi-jet meters cost less. They do not need external power if you use a mechanical register. Electromagnetic meters give better accuracy and no moving parts. Multi-jet meters have moving parts but are simple to repair.
One customer in Vietnam asked us for a flow meter to measure diluted chemicals in a food processing line. The pipe size was DN25. The liquid conductivity was 1800 µS/cm. We supplied an electromagnetic flow meter with 316L electrodes and PTFE lining. For pure water below 20 µS/cm, an electromagnetic meter may not be the best option. In that case we help the customer select an alternative principle.
What to Send Us for a Fast Quote
Send us the fluid name. Send the pipe size in DN. Send the normal and maximum flow rate in m3/h or liters per hour. Send the pressure in bar and temperature in °C. Tell us the output signal you need. If you have a data sheet from an existing installation, send that too. We will return a matched technical sheet and price quote within 24 hours.

FAQ on Electromagnetic and Multi-Jet Water Meter Specs
1. What minimum conductivity is required for an electromagnetic flow meter?
Most Silver Instruments electromagnetic flow meters need 5 µS/cm or more. For liquids below that value, we will suggest another flow principle.
2. Can a multi-jet water meter handle hot water?
Standard models handle 50 °C. Choose a hot water version for 90 °C service. Confirm the fluid temperature when you request the quote.
3. What accuracy can I expect from each meter type?
Electromagnetic flow meters give 0.5 percent of reading as standard. Multi-jet water meters usually give Class 2 accuracy under ISO 4064.
4. Do these meters support remote output signals?
Yes. Electromagnetic models support 4-20 mA, pulse, RS485 and HART. Multi-jet models support pulse, M-Bus and RS485.
5. How fast can Silver Instruments send a technical sheet?
Send your application data by WhatsApp or phone. We usually return a technical sheet and price within 24 hours.
